Yesterday, we brought you the news of Sir Paul McCartney's and the remaining members of Nirvana's collaborative performance at the 12-12-12 Hurricane Sandy relief concert at Madison Square Garden. Sirvana (Nirvcartney? McCartvana?) performed an original song titled “Cut Me Some Slack,” which you can pre-order on iTunes. Hear a preview clip of the song and watch the live performance below. 

The song will be featured on the soundtrack for Dave Grohl's Sound City film.
