This has to be some kind of 12-12-12 joke, right? Via Huffington Post:

If a curious report from the Sun is to be believed, Sir Paul McCartney will front a Nirvana reunion with Dave Grohl and Krist Novoselic at Wednesday's massive 12-12-12 benefit concert.

The event is set to take place at Madison Square Garden and will benefit Hurricane Sandy victims (a live stream of the concert will be available on HuffPost Entertainment). McCartney would reportedly take the place of the late Kurt Cobain.

“I didn’t really know who they were," the Beatle said of being in the studio with Grohl and Novoselic. "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 12-12-12 benefit concert features an impressive line-up, including Bon Jovi, Eric Clapton, Dave Grohl, Billy Joel, Alicia Keys, Chris Martin, The Rolling Stones, Bruce Springsteen & the E Street Band, Eddie Vedder, Roger Waters, Kanye West, The Who and, of course, McCartney.

There is NO WAY Grohl and Novoselic would agree to something like this. None. Zero. Maybe they'll play together—that might be kind of cool, in fact. But playing with McCartney is NOT a Nirvana reunion—that's three notable musicians jamming, which happens all the time. The only way it'd be a "Nirvana reunion" is if they played a Nirvana song. But they will absolute not be doing a single Nirvana song. They wouldn't. Ever.
