According to a report in The Sun, Paul 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.”
