The organizers of a "12-12-12" Hurricane Sandy benefit concert are playing coy, but rumors are flying fast that Sir Paul McCartney will step in to Kurt Cobain's shoes as Nirvana frontman for the event Wednesday night.
The Sun reports that McCartney has been secretly working with Cobain's former bandmates, Foo Fighters singer Dave Grohl and bassist Krist Novoselic, in preparation for a Nirvana reunion almost 20 years in the making.
McCartney told The Sun he called up Grohl to "jam with some mates" for a studio session, where they went on to "just make something up."
That "something" is rumored to be the song the guys will play at Wednesday's show.
"I didn't really know who they were," McCartney said. "They are saying how good it is to be back together. I said, Woah? 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."
Cobain committed suicide in 1994.
The Foo Fighter's Twitter feed has been active as well dropping hints at something special.
