WATCH: Noel Gallagher catches the tube to perform on stage with U2

Keeping in theme with U2’s Innocence + Experience tour, the band invited some special guests to the stage during their six-night run in London’s 02 arena.

Last night, Noel Gallagher joined them on the encore for 'I Still Haven't Found What I'm Looking For' and a rendition of The Beatles’ 'All You Need Is Love'.

"We'd like to bring out one of my heroes, one of the band's heroes, to help us with this next tune," Bono said as he introduced Gallagher

"Will you welcome to the stage the high flying bird himself Noel Gallagher."

Only moments before the former Oasis singer performed in front of 20,000 fans with one of the biggest bands in the world, he jumped on the London Tube.

As you do.

Very rock and roll - never change Noel, never change.
