Newly created all-star group 5th Story - which features Gareth Gates and Dane Bowers - say they could see themselves carrying on into the future, despite being assembled simply for the ITV2 series The Big Reunion.
The five-piece is made up of performers who have had either solo careers or a stint in other groups and viewers will see how they get on during a second series of the show.
Until now the programme has focused on defunct groups being brought back together and acts such as A1, 3T and three-quarters of Eternal will be seen regrouping in the latest run.
Launching the series today, members of 5th Story said after a few days of rehearsal they were getting on well.
Bowers said it would depend on the response from fans whether the collaboration would continue beyond the show.
"It does need to be right - people have really got to love it for it to work. At the minute we get on and we're having fun. There is definitely scope for us creatively to move on," he said.
"We didn't know if it was going to work, but there's some talented people in the band."
Nineties pop acts who reformed for ITV series The Big Reunion are to release a Christmas cover of Wizzard's 'I Wish It Could Be Christmas Everyday'.
The charity single, released on December 15, will feature groups including Blue, Atomic Kitten and Five.
All proceeds will go to ITV's Text Santa appeal, which raises money and awareness for six UK-based charities including Age UK and BeatBullying.
Liz McClarnon from Atomic Kitten said: "When we started the talks for The Big Reunion this time last year, we couldn't have imagined we'd end up recording a Text Santa Christmas single. It's all for charity and we are so humbled to be a part of it."
They'll battle this year's X Factor winner, among other acts, in a bid to top the festive charts.
