The Take That star will tour the U.K. to find boys who can perform like the group, which also includes Mark Owen, Howard Donald and former bandmembers Robbie Williams and Jason Orange, in a nationwide musical stage show called The Band, which will feature the music of the hit group.
The eight-week talent search will air on the BBC under the current working title of Let It Shine, a reference to a Take That lyric. Gary will be judging the competition, which tests singing and dancing skills, plus stage presence, alongside three currently unannounced mentors.
“Back in 1989, we were just a group of normal guys from Manchester who came together to become Take That," Gary Barlow said in a statement. "The secret to our success was that each of us brought something different to the group and that the five of us had real chemistry. Now with Let It Shine we're looking for people from all walks of life to form another unique group who can recreate that magic. If you think you’ve got what it takes, we want to see it!”
"Extremely excited about this. A new Saturday night show on @BBCOne!," Gary wrote on Twitter. "Can't wait to see what talent is out there! We're looking for guys to perform the songs of @TakeThat for a new show."
Auditions take place in July and August (16) while the show will film in September (16) and in 2017. It is thought Let It Shine will be filling in the gap where The Voice U.K. used to be following its move to rival channel ITV.
Gary, who has previously judged on Britain's The X Factor, will be joined by co-hosts Graham Norton and The Great British Bake Off presenter Mel Giedroyc.
Robbie famously left the group in 1995 to go solo, but returned for their 2010 album Progress and a tour in 2011 before leaving again. Jason left in 2014.
