Watch Nirvana’s Krist Novoselic Perform “Helter Skelter” with Paul McCartney

Last night during his concert in Seattle, Beatles icon Paul McCartney welcomed Nirvana’s Krist Novoselic to the stage. No, they didn’t jam on “Cut Me Some Slack” from the Sound City documentary soundtrack, rather they took a go at the one-and-only “Helter Skelter.”

“We walked in; we jammed the song. It just came out of nowhere,” once said Dave Grohl with regards to how ‘Cut Me Some Slack’ came to life. “The best songs happen that way. We recorded it live and put a vocal over it and that was it. It was three hours and it was perfect.”
