Paul McCartney may be set to front a Nirvana reunion, of sorts, according to The Sun. The London-based newspaper has reported that McCartney will join Dave Grohl and Krist Novoselic for a performance tonight at a benefit show in New York for victims of Hurricane Sandy. The report says the former Beatle recently joined Grohl, Novoselic and guitarist Pat Smear and for a jam session, and implies McCartney will play a fill-in role for Kurt Cobain. “I didn’t really know who they were,” McCartney said, of being in the studio with the band. “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 Huffington Post attempted to confirm the report by contacting organizers of the benefit, as well as McCartney's representatives. None would offer details, and instead advised that people tune in to the show and see for themselves. The concert will be televised in North and South America, Asia, Europe, Africa and Australia, with a potential 2 billion viewers. In the United States alone, 34 television networks will air the event.
