Noel Gallagher is adamant his former band Oasis became a "sham" in later years because he had to pretend to be pals with his brother Liam onstage.
The Wonderwall hitmakers split in 2009 after a backstage bust-up between the guitarist and his singer brother minutes before they were due to perform in Paris, France.
Gallagher admits he and Liam always struggled to remain on friendly terms throughout the history of the band - but he insists their relationship deteriorated so badly in the years before the break-up, it felt false to play gigs together.
He tells Britain's Telegraph magazine, "There's always a power struggle in a band, and when you're young and daft and hopped up (sic) on drugs and alcohol, it can get violent. But when you're all grown men with kids, it just doesn't feel right.
"I found it quite undignified. We're supposed to be the elder statesmen now! All this effing and blinding before gigs, and then going up and singing Live Forever. It was all a bit of a sham, really."
