Collabro are reportedly a big target for 'Britain's Got Talent: Champions'.
ITV bosses are said to be desperate to sign up the group - who won the eighth series of the show in 2014 and consist of Michael Auger, Jamie Lambert, Matthew Pagan and Thomas J. Redgrave - for the new show, but they are keen to bring back Richard Hadfield, who quit the band in June 2016.
A source told The Sun Online: "Producers are desperate to get the whole band back together, as it would make great TV to show them talking through their issues and working things out - then reuniting on stage together.
"It would spark interest in the band again and they would think viewers would love to see them back together as they were then."
However, another source suggested any return would just feature the current lineup.
The insider said: "The band as they are now have been in talks with 'BGT', Richard left years ago so there's no reason why he would be part of it."
Following the success of 13 series, the ITV talent show is going to be getting together the winners and other memorable stars so they can battle it to decide who is the ultimate champion of the show.
It has already been confirmed that Susan Boyle - who shot to fame when she finished second in 2009 - is on the line-up after she recently impressed judge Simon Cowell on 'America's Got Talent: The Champions' when she made it to the final 12.
The singer could also be joined by 2012 winner Ashleigh Butler, who triumphed on the programme with her dancing dog Pudsey, who sadly died in 2017.
She now performs alongside his replacement Sully.
