After a gigantic two hour 20 minute set at London’s O2, U2 were joined by Noel Gallagher to cover two Beatles songs.

Introducing the Oasis member to the stage, Bono said: "I’d like to bring out of one my heroes, one of the band's heroes to help us out with this next song. Will you welcome to the stage the high flying bird himself Noel Gallagher.”

The group then went into U2 classic "I Still Haven't Found What I'm Looking For”, followed by The Beatles “All You Need Is Love”. See fan-filmed footage below.

According to NME, Bono invited two brothers on stage, handed them acoustic guitars, and asked them to strum along to “Angel of Harlem”.

The full setlist contained over 25 songs, including "Where The Streets Have No Name”, “With Or Without You” and a host of songs off their new album.

Their Innocence + Experience tour continues, the band playing five shows at the O2 Arena.
