This week, Wings frontman Paul McCartney teamed up with the surviving members of Nirvana (Dave Grohl, Krist Novoselic, Pat Smear) for a special performance at the 12-12-12: The Concert For Sandy Relief benefit show. The resulting jam, "Cut Me Some Slack," was far heavier than anything McCartney has previously been associated with (like a mix of "Helter Skelter" and "Scentless Apprentice"). Now, you can listen to the studio version of the song below!

The song was cut for Grohl's documentary film Sound City, his directorial debut about the legendary Van Nuys, California studio of the same name. The soundtrack, which is now available for preorder on iTunes, has some other crazy collaborations with the likes of Trent Reznor, Stevie Nicks, Josh Homme, members of Foo Fighters, Cheap Trick, and Rage Against the Machine, and Rick Springfield. You can see the full tracklist here.

As we reported earlier, tonight's Saturday Night Live will go on as expected with Martin Short as the host and McCartney as the featured musical guest—maybe he'll bring the Nirvana dudes back for another performance?
