How did One Night Only form?
"We formed back in 2003, actually. We all grew up in the same area and went to school together. I was actually a late addition to the band - I met the rest of the guys through the drummer's brother. I was always going up to their house and watching them play, and eventually I just became the lead singer and lead guitarist."
Is it true you started as a Beatles cover band?
"There's a slight truth to that. We used to play a couple of Beatles songs, but people have really latched onto it and started calling us a 'Beatles cover band'. It's all gone a bit over the top, because we used to do a huge mix of covers - modern guitar music, chart hits, a bit of everything."
Who are your influences?
"Again, a bit of everything. I don't just like recent stuff, but old stuff too. David Bowie, Bob Dylan, the Killers and Arcade Fire are some of the main ones."
Where did the band's name come from?
"It came from our first gig, because we didn't have a name and it was, as always, 'For One Night Only'. It just kinda stuck."
Your new single, 'Just For Tonight', is heading for a very respectable chart position on Sunday. What's it all about?
"It's inspired by a weekend we spent recording a demo by this huge power station. There was this big power surge that, at night, just looked totally insane - it looked like a big light display! We really wanted to put that huge, powerful vibe into a really anthemic song, and 'Just For Tonight' was the result."
So next time you want to write an anthem, you'll know where to go...
"Haha! I guess so, yeah. The bigger the surge, the better for us."
The song was used as the theme toNearly Famous, a teen drama series shown on E4 last year. How did that come about?
"I think one of the directors had come across the song and instantly said: 'I wanna use this'. I'm pretty cool with it, you know. The song seems to suit the show."
Is your album full of songs like 'Just For Tonight'?
"It's quite diverse, and there's a lot of progression as the album plays through - the songs get bolder and bigger. It's not just full of pop songs like the first two singles - there's a lot of different flavours in there. People will be surprised, but not in a bad way. They'll be glad that it doesn't all sound like 'Just For Tonight'."
Where do your lyrics come from? What are you inspired by?
"I try to tell stories from my life, really. I like my lyrics to be as real as possible. I have a little book that I keep on me, and I try to keep everything logged, so it all just comes out when it wants to, I suppose."
You've just started a five-week UK tour. How's it going?
"It's starting to sell out quite rapidly now, actually. We're really excited to be doing our own shows, because we've got an amazing fan-base now. We're even more excited than the fans!"
What sort of a person is a One Night Only fan, do you think?
"From what we've seen at the shows so far, it's probably about 50% teenage girls. There are boys too, and also a few couples. I think our music's really appealing to a whole range of audiences."
Has your dressing room been invaded yet?
"Not as yet, no. I'm sure it's coming though - we're going to need better security on this tour!"
What's the atmosphere like on the One Night Only tour bus?
"It's great, 'cause we're all best mates and it's not often you find a band that can get along with each other all day long. Because the band grew so organically, that's the way it's always been. We're all on the same wavelength so there's a really happy atmosphere."
Do you think that will continue as you spend more and more time together?
"Actually, the more we've toured together, the more we've bonded and stuff. We've also got a lot more ambitious, so we're really excited about the future. Watch this space!"
'Just For Tonight' is out now. One Night Only's debut album, Started A Fire, follows on Monday.
