Paul McCartney to front Nirvana for a benefit concert?

Will Paul McCartney fill the role of Kurt Cobain for a Nirvana reunion? Representatives won't confirm anything, but rumors say the group will perform a new song with the former Beatle.

As if Nirvana partially reuniting wasn’t enough for some music fans, the band will reportedly have a rock legend stepping in for lead singer Kurt Cobain: Paul McCartney.

Nirvana’s remaining members are set to reunite for a concert scheduled for tonight that will benefit victims of Hurricane Sandy and will take place at Madison Square Garden in New York. The surviving members of the band, current Foo Fighters singer and former Nirvana drummer Dave Grohl, former Nirvana bassist Krist Novoselic and somewhat honorary member guitarist Pat Smear, who toured with the band in the six months before lead singer Kurt Cobain’s death in 1994, will all take the stage.

According to the Guardian, the group will be playing a new song with McCartney, not a Nirvana classic. The Guardian reported that McCartney was the one to suggest doing something new.

“I didn’t really know who they were,” McCartney said, according to the Sun. “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.”

Grohl invited McCartney to participate, according to the Guardian.

Representatives for McCartney and for the 12.12.12 concert have not commented, with a representative for McCartney telling SPIN that they could "neither confirm nor deny" the rumor. The concert will also feature The Rolling Stones, Jon Bon Jovi, Kanye West, Billy Joel, Bruce Springsteen and Eric Clapton.
