Louis: "Olly, you are the dark horse of this competition. I watched you at home and you're getting better and better. I liked that you didn't pick a predictable song, you picked an unusual song. It was fantastic. You're the boy next door, you can sing, you can dance, and you're very, very likeable. You're here for a long time."
Dannii: "My friend, that was one classy big band performance. Olly the entertainer. You've been working with [Michael] Bublé, who has spent years working at the craft of milking every word and phrase, and you did that as well as all the dancing. I absolutely loved it."
Cheryl: "What I love about you is you're really coming into your own each week and growing a little bit more. I think I'm going to thoroughly enjoy watching you throughout this process. You get better and better each week."
Simon: "Once again, you're back in your comfort zone. I loved the two dancers - I know what it's like working with two witches. Joke! And you know, girls [Cheryl and Dannii], it's not about being smug, it's about looking after your contestants. What we've been able to sort out is what kind of artist you should be. The whole point in making big band work is you've got to have style, you've got to have charisma, and you've got to have confidence. You scored on all three."
Louis: "Lloyd, little Lloyd from Wales, I'm a big supporter of you. I know big band's not really, really your thing. If I was doing a boyband in the morning, I'd put you as the lead singer, but I think you need to be in a band. I think as a solo artist you're a bit lost. I don't think you've got the confidence. And I've never seen Frank Sinatra do a backflip, so I don't think the backflip was great."
Dannii: "I totally disagree! I think the backflip was entertaining. Somewhere halfway through you hit your stride and got comfortable. But up until halfway I was looking in your eyes and you were doubting yourself a little. It took confidence to get back on your feet and big band is not your strength. You need to be filling every phrase of the song, not waiting until the big note and you get it."
Simon: "I think your issue is you've got to get some confidence. It was quite obvious at the start you didn't have much confidence. You were looking over at Cheryl for confidence. When you're good, you're very good. There were tiny moments in the song where I thought you were very good. Having said that, doing a backflip when singing 'Fly Me To The Moon' is like eating a sandwich while swimming. You don't do the two together, it doesn't work. I think you've got to sort your head out right now. One thing we don't do is patronise and you've got to get better."
Cheryl: "The criticism last week knocked you. I totally get it. I watched it back and thought you were fantastic, by the way. Tonight was about coming out here and having fun. The backflip was a bit of fun and showed the youth in the song, and these lot [the audience] absolutely loved it!"
Dannii: "Girls, all I have to say tonight is you are back in the race! You really came back tonight with your strength and what made you unique in the first place. Shar, you stepped up."
Cheryl: "I absolutely loved it. This is why we loved you in the beginning. You updated a classic and gave it attitude. Graziella, I loved your rap and this is what you're about. This needs to continue, it's what makes you original. Absolutely fantastic."
Simon: "This is the first time since the live shows when I actually started to believe in you as a group. You look completely different to what you did last week. You look fantastic, you sounded much better and I can actually now see some chemistry between the three of you. What I like about you, particularly you, Graziella, is that you can take criticism, unlike others, on the chin. There's no point kidding yourself, it wasn't good last week, and you understood that and came back fighting. It was a million times better and I genuinely hope you stay in the competition."
Louis: "Girls, all I can say is I'm really proud of you. I watched you from home last week, it wasn't great, but you're a different group tonight. You look like a world class girl group and there's a big gap in the market. Graziella, I loved your rap, Shar and Shaniece you were brilliant. All I need now is for people to vote for you. I believe in you. Fantastic."
Louis: "Rachel, I could not believe last week you were in the bottom two. I can't understand, you're an amazing singer. You own the stage. I'm glad you've got your confidence back. People, give Rachel a chance, she deserves to be on this stage. Pick up the phone and vote."
Cheryl: "You've got guts, you've got determination, you're full of personality, and most of all you can sing, girl! You know what, whenever I speak to my boys about who they get on with, it's you they're always talking about. Hope tonight is your night and the public vote for you, because you deserve to be in the competition."
Simon: "I've got no idea who you are because you're not the person we've been seeing for the past two weeks. Literally, it's like seeing a brand new competitor. The last two weeks you were acting Louis's age, to be honest. You've been too serious. You've lost the silly haircut and started to have fun. It was a great vocal, a superb performance, and for the very, very first time I'm starting to see the person you really are. And again, no whining. You just came back and proved a point. I think you are in with a shot now. Congratulations."
Dannii: "Rachel, that's how it's done! I just want to thank you for putting up with me. I don't think I've got it right with you up until now. I'm listening to the criticism, taking it on board and putting it into your performance. I know you do the rest so easily, so thank you, thank you, thank you."
Louis: "Jamie, I'm a little bit confused. The theme this week is big band and you come out and sing a U2 song. It's not big band, Bono wouldn't want it filed under big band. I know your mentor Simon changed the song, but I feel like it's cheating on everyone else. You're a great performer but that was like a karaoke version of a U2 song. I don't think it's fair. I don't blame you, I'm blaming Simon. There are rules in the show. I wouldn't get away with it and neither would the girls."
Dannii: "It was rich, you're a true pro to get up and do that. I don't think it had the magic of last week, but you're a great performer. You can own the stage just by yourself."
Cheryl: "It's really tough to have 24 hours to learn a song, come out and perform. I've got to give it to you for that. Parts of the song I thought, 'Wow, it's really going somewhere', but to be totally honest with you it didn't excite me as much as last week. But well done for coming out and singing it."
Simon: "I agree with what they said. It wasn't as good as last week, but that's because we had 24 hours to prepare. I think I made the right decision. I think you lost your way at one point towards the end, but for Louis to sit here like someone who works for the council with a silly little rule book... I don't think [Louis] is in a position to preach to us about musical taste knowing about the two horrors [John & Edward] who are about to come up."
Louis: "Stacey, all I can say is wow. What a transformation. I loved your song, I loved the song choice. It was incredible. You definitely got the emotion, and everybody loves you, Stacey. Everybody loves you."
Cheryl: "I'll start off by saying you look like a little princess! You look absolutely beautiful in that dress. For me it wasn't the best I've heard you sing, but I still enjoyed it because I just love you, Stacey."
Simon: "I agree with Cheryl, I think you looked better than you sounded. I really, really, really do like you. I know when I criticise you everyone boos, but I want you to do well. I thought it was just a bit robotic, but the second half was better. So you've got to learn to perform songs. At the moment all you're doing is standing the middle and singing. You're not doing anything else."
Dannii: "I think I should explain that you had your hardest week this week. Stacey came to me and locked the door and was in floods of tears. Everybody has a week where they hit the wall. I'm so proud of you for getting up there and doing it. I know you can do it. No-one appreciates this more than you do."
Louis: "Danyl, some people were born to sing and entertain and you're absolutely one of them. You owned the stage and took on a really big song. I think you're unstoppable in this competition and I think it was the most authentic performance of the night."
Dannii: "Danyl, I have a lot of respect for you for making that your version. It's been covered many times but that was very good. And you look hot!"
Cheryl: "You look the part, you sounded the part, it was a great song choice. It was another great performance for Danyl Johnson."
Simon: "I think we've got to remind ourselves what we're looking for on the show. We're trying to find someone who can represent this country all over the world, and I don't think you've had enough credit in the competition so far. Week after week you go out there and give 150%, and in my opinion that was in a completely different league to anything else we've heard so far."
Louis: "Joe, I know you were so nervous. I want to tell everyone at home you're one of the nicest contestants. Backstage, you're always so nice. You've absolutely got likeability. You're going to be in the competition until the very, very end."
Dannii: "Yes, you're such a nice guy, you sing perfectly every time and no-one makes me smile more, honestly. You managed the snake hips very well! It's just that your other performances, you've taken on mature songs, and maybe with the older dancers you looked like a little boy. It's not a bad thing, you're cute and it won't go against you. Please stay in the competition."
Simon: "I have to hand it to you. Whatever's thrown at you, you rise to the challenge. You sang very well. I didn't think the performance was particularly authentic - you've got about as much Latin flair as a dolphin, because that's not you. The important thing with you, because you are going to be in the competition next week, is you've got to prove you're a recording artist and not just a cutesy performer. There is a difference."
Cheryl: "I think you showed you can sing in the last two weeks, and tonight you showed you can perform. It was sparkly, sexy, and I thoroughly enjoyed it. I loved it."
Louis: "Lucie, there must be something in the water in Wales, because they keep churning out great performers. That was a great, amazing performance. It's a classic song and there were no tricks, no dancing, no dancers. You did the hardest thing - it was just you and your voice. It was an incredible performance."
Cheryl: "I have to say, Lucie, in the past two weeks something was not connecting, but tonight you absolutely proved me wrong. That was stunning. Beautiful. It was effortless, all over your face, it was authentic. Just beautiful. That's the first thing that's given me goosebumps tonight, well done."
Simon: "I thought it was a very, very good vocal. Far, far better than what we've heard before. Having said that, you sang it like an actress. I didn't get what I wanted to get out of it. It was a good performance, but I don't know what it was. It's difficult to describe. It was a great vocal... maybe it was just a vocal."
Dannii: "Can I just say, that was just sensational. It was classy, it was the best performance, and I want to thank Cheryl for her comments last week. I don't think I chose the right things for you before, but this was amazing. I don't appreciate Simon's comments - you cannot fault that performance. He's scared of you!"
Dannii: "Well, guys, that was some performance. I mean, you are the luckiest brothers ever - those girls were hot around you! You know what, I'm really torn here because I don't know what to say. The singing isn't of the standard that's going to follow Alexandra Burke to win the show but it's entertaining. I don't want you to take a spot away from my girls but you know, it was a great performance."
Cheryl: "John and Edward... Right. OK. You know what, you are two of the nicest kids I've ever met. I think the boos are pantomime, don't take it on board. You know what, you're becoming my guilty pleasure. Each week I can't wait to see what you're going to come out with next."
Simon: "I don't think I can do this anymore. OK, let me try and be constructive here... and I'm struggling. Look, if you heard it on the radio, it would probably be one of the worst things you ever heard, but I give you some credit for at least putting on a show and having fun. But then I take it back to being a singing competition, and this is appalling."
Louis: "Simon, it is a TV show. You're never going to please all the people all of the time. Simon signed an act once called Zig and Zag, and you're better than them! You're getting better and it was your best performance yet. Some people are rude in the audience. Some people like them and some people are going to vote for them."
