Noel Gallagher took the London Overground to U2‘s gig at the city’s O2 Arena on Monday night (October 26).

The former Oasis guitarist was spotted on the tube by fans ahead of his onstage cameo with the Irish band. See a photo below.

Gallagher joined U2 onstage as the band continued their Innocence + Experience tour of the UK.

He joined the Irish four-piece at the end of their two hour-plus show on acoustic guitar and backing vocals for their classic hit single ‘I Still Haven’t Found What I’m Looking For’ and a cover of The Beatles’ ‘All You Need Is Love’, footage of which you can watch below.

“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,” Bono announced to the crowd before Gallagher took to the stage.

Gallagher told Absolute Radio last year that he “loves” public transport in London: “I have an Oyster card, I’m always on the tube. I love the tube.”

Asked if he ever gets hassled by fans when using public transport, Gallagher added: “A Scottish couple were sat opposite me on the tube once and they were kind of muttering to each other and staring. Then one of them said ‘Excuse me mate, which stop is it for Buckingham Palace?’ That was it, they were asking me for directions. I’ve never been minded on the tube.”
