Paul McCartney Helps “Reunite” Nirvana. Watch “Cut Me Some Slack” with Dave Grohl, Krist Novoselic and Pat Smear

We were teased with a Nirvana “reunion” tonight with Paul McCartney. Thankfully, we didn’t hear Sir Paul attempt to channel Kurt Cobain on “Pennyroyal Tea” or “Lounge Act.” Watch him perform the new song “Cut Me Some Slack” with Dave Grohl, Krist Novoselic and Pat Smear and make a donation to the Hurricane Sandy relief fund at 121212concert.org
