North Shore were eliminated from The Sing-Off on Monday night following their performance of 'The Power of Love' by Huey Lewis and the News on 'Guilty Pleasures Week'. The Deltones were also sent home in the episode.
Speaking to Digital Spy about the remaining groups, he said: "We were in a competition but we were all brothers and sisters. I couldn't believe how great these people were - it totally blew me away."
Guy went on to recount an incident involving Dartmouth Aires, saying: "I remember watching Michael once, I was so amped that I came out and sang my song but was so pumped up I sang it in totally the wrong way.
"The judges and producers said, 'Guy what are you doing?' I said, 'I've just got done watching Michael, I gotta calm down!'"
North Shore had initially chosen 'MmmBop' by Hanson for their track this week but changed at the last minute to 'The Power of Love', something which Guy says was a probable factor in their elimination.
"It seemed like these younger people could catch on to things a lot faster than we could! So for us to learn choreography and a new song..." Guy explained to reporters on a conference call on Tuesday.
"I think I actually made mistakes in the lyrics because I hadn't even got them memorized. On the last day we changed the arrangement and the choreography and it was hard for us to digest everything and spit it back out on stage and still be having a good time. The main thing for North Shore being on stage is that there is no nervousness, we don't have to get loose - we are at home on stage."
Guy, who said that the best advice the group received from the judges was to take songs and make them their own, also shared that his favourite performance from the season had been their rendition of Bruno Mars's 'Lazy Song'.
"The thing for us was to do a new song and try to get out of the dark ages," he said. "I think because that was a new tone and everybody that was on the show and viewing the show is basically in a certain age group, it meant more to them than the other songs we'd do from our generation because they knew it.
"We had fun with it and it was a fun performance - the choreography and the props we used. Well, the choreography for us was sitting in a chair! That was my favourite."
As for the future of the group now, he told Digital Spy that being on The Sing-Off had reaffirmed his belief that he was born to perform, admitting that this time last year he had been considering giving it all up.
"We were quite different to everyone else out there simply because since 1965 when I was 14 this has been my job - to perform," he explained.
"At this point last year I was thinking about, 'This has been our worst year in the business' and I guess it goes for all business in this economy, and was maybe even thinking about leaving the group and getting a regular job to be with my family.

"In 2009 my namesake, my son Guy, passed away. It was a very traumatic episode in my life so family became even more important than it was before, and with the tough economy and business not being so good and it being difficult to travel back and forth to all the places that we go, I was thinking about maybe throwing in the towel and getting a regular job so I could be with my family.
"Being on the show I just realised, 'I just can't do it'. This is me. I define myself by this. We just have to hopefully take this experience and this wonderful opportunity to be on The Sing -Off and use that to get to another level.
"I hope we can take this and keep on going. I don't want to quit singing."
The Sing-Off airs Mondays at 8/7c on NBC
