Former Beatle Paul McCartney took a jacket intended for Bono to wear during their 2005 Live 8 duet without his permission.
The U2 frontman was stunned to see the former Beatle sporting his clothes when they teamed up on stage for Sgt Pepper's Lonely Hearts Club Band - but was too starstruck to demand it back.
He says: "(McCartney) asked our wardrobe person whose it was, and she says: 'Bono's, he's wearing it today.' And (McCartney) says: 'No he's not. I'm wearing (the jacket).'
"Now, I'm used to being the big guy, but not in front of a Beatle. I went out in a denim jacket instead."
