Gary, who has been a member of Take That since their formation in the early 1990s, explained that it's important not to let arguments get the better of them and cause rifts within the group.
He told The Sun: "There will be rows in a band but you are brothers.
"They might be close sometimes and sometimes not, but it’s part of the foundations - the boys have to take care of one another and look after one another. You are having an amazing run and it's brilliant. You can't walk away from that - why would you?"

"If there’s any suggestion of trouble, they need to hang on in there. It’s way too early to be thinking about splitting up."
Meanwhile, it has been reported that Gary recently gave Robbie Williams an ultimatum, claiming he has until May to decide if he wants to rejoin Take That for their next album.
Robbie returned to the boyband in 2010, having been away from the band for 15 years. They topped the charts as a five-piece with their album 'Progress', though since then Robbie has had two number 1 albums as a solo artist.
