Take That said there is still a chance past band members Robbie Williams and Jason Orange could return to the group.
Williams left Take That in 1995 but returned to the band in 2010 for a short period.
Meanwhile, Orange left the British pop group in 2014.
Whilst speaking to Good Morning Britain today (GMB) at the premiere of Greatest Days - a film based on the Take That jukebox musical of the same name - Gary Barlow didn't rule out the possibility.
On the idea of Williams and Orange returning he said: "When the time's right it'll happen".
Fellow Take That band member Mark Owen added: "I'm not sure, we all hope one day it might happen.
Will we ever see the likes of @JasonOfOrange and @robbiewilliams back in the band for one night? 🙏 🎶@GMB asks @takethat at the premiere of Take That Musical film. pic.twitter.com/F7adyPxU00

"It wouldn't surprise me if, you know, it (a full Take That reunion) happened, but it wouldn't surprise me if it doesn't."
Meanwhile, when Howard Donald was quizzed about a possible reunion with fellow band members Williams and Orange he said he was unsure.
Donald said: "I don't know. I don't think Jason ever, but maybe possibly Robbie, but not Jason."
