James Corden joined Snow Patrol on stage during their gig at the Royal Albert Hall in London on Tuesday.

The Gavin and Stacey star duetted with the band on a special rendition of ‘Set The Fire To The Third Bar’.

Snow Patrol frontman Gary Lightbody asked the actor to perform with the group after they spent a night drinking together last week.

“I thought he was joking, then he started singing in the bar and I nearly fell off my chair,” Lightbody said.

"He was brilliant! So we thought why the hell not, doesn’t always have to be a female guest vocalist.”

Corden, who sung the part that was originally performed by Martha Wainwright, said he was honoured to appear on stage.

“I was so sure he wouldn't remember I said yes, and before I knew it I was getting calls about soundchecks and everything,” he said.

“It's an honour to sing with one my favourite bands and I loved every single minute of being on stage with them.”

Earlier this month, Girls Aloud star Cheryl Cole performed Wainwright's part with the band at the same venue.
