Noel Gallagher's friendship with Bono has been documented in the past, but few would have reckoned that it would stretch as far as appearing on stage with U2.
However, that's exactly what happened on Monday when the former Oasis man joined the Dubliners on stage at London's O2 to play guitar on 'Still Haven't Found What I'm Looking For'.
Heck, he even joined in on a bit of the singing, and on a cover of 'All You Need is Love', after Bono described him as 'one of [his] heroes'.
Gallagher proved himself a man of the people after he was spotted taking the tube to the O2:
