Krist Novoselic comments on the collaboration with Paul McCartney

“Dave, Pat and I hadn’t played together for 20 years, until last year, when we were in the room with Paul McCartney, of all people [for the session in Grohl’s film, Sound City]. I’m like, “Oh, my God.” I love the man. And he’s a left-handed guitar player, like Kurt. He’s playing this mean slide. I start playing, trying to catch the groove, in drop-D tuning with the old Rat distortion pedal to get some growl in there. Dave’s playing, there’s Pat. Paul shoots this riff at me, I pick it up. I shoot something back at him, he picks it up.

All of a sudden, this song comes together [“Cut Me Some Slack”]. It came together in an hour. I looked at Dave and Pat and kind of forgot about Paul. I was like, “We haven’t done this in so long.” It’s like we walked out that door 20 years ago, we walked back in and it was all still there. In the film, when Paul says, “I didn’t know I was in the middle of a Nirvana reunion . . . “
