Paul McCartney Reportedly Replacing Kurt Cobain in Nirvana Reunion .

We should’ve known this date would bring about some weird news. The Guardian reports that Paul McCartney is set to take the place of Kurt Cobain during a set at tonight’s 12-12-12 Hurricane Sandy benefit concert at Madison Square Garden.

Surviving members Dave Grohl and Krist Novoselic haven’t played together in 20 years—save a few one-offs and Novoselic’s appearance on the latest Foo Fighters album—but will perform a new song they’ve been working on with McCartney.

According to a spokesman, Grohl asked McCartney to jam recently and the music icon found himself playing with the whole band—including guitarist Pat Smear, who toured with the band near the end of its career and is also a member of Foo Fighters.

“I didn’t really know who they were,” McCartney was quoted in the article. “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.”

12-12-12 The Concert for Sandy Relief will bring together the likes of the Rolling Stones, Kanye West, Bruce Springsteen and as the above proves, much, much more. It begins tonight at 7:30 p.m. EST and will broadcast live on select television networks and in select theaters. It will also stream online.
