Paul McCartney could be set to join the surviving members of Nirvana onstage at a charity gig tonight (December 12).

According to a report in The Sun, McCartney will join Foo Fighters’ singer Dave Grohl and Krist Novoselic onstage, replacing Kurt Cobain as singer, at a benefit for the victims of Hurricane Sandy in New York.

According to the newspaper, McCartney rang Grohl who asked him to come and “jam with some mates” and then found himself playing with Grohl on drums, Novoselic on bass and Pat Smear on guitar. The report then quotes McCartney as saying: “I didn’t really know who they were. They are saying how good it is to be back together. I said ‘Whoa? You guys haven’t played together for all that time?’ And somebody whispered to me ‘’That’s Nirvana. You’re Kurt.’ I couldn’t believe it.”

The Rolling Stones, Bruce Springsteen, Bon Jovi, Green Day, Kanye West and The Who are all set to play the 121212 concert tonight.

Paul McCartney is reportedly working on a new album, the follow-up to this years’ collection of covers Kisses On The Bottom. Producer Ethan Johns recently told NME that he had been in the studio with him, along with Mark Ronson. Adele producer Paul Epworth is also reported to be working on the record.

Meanwhile Dave Grohl is working on his documentary Sound City about the legendary California recording studio Sound City, where classics such as Fleetwood Mac’s Rumours and Nirvana’s Nevermind were recorded. It is set to be premiered at the Sundance Film Festival in January 2013.
