Foo Fighters frontman Dave Grohl has revealed the identity of another special guest on the band's upcoming album Concrete And Gold, telling ET Canada that Paul McCartney plays drums on a track. Grohl explained, "He's a pal. We've known him for a long. He's great. He's the most wonderful person in the world. He's a great guy."
Grohl and surviving Nirvana members Krist Novoselic and Pat Smear previously collaborated with McCartney on a song called "Cut Me Some Slack" for Grohl's 2013 documentary Sound City. Grohl told us at the time that they were so starstruck working with McCartney that they didn't realize how momentous the occasion was: "When we were recording the song with McCartney, that really was the first time Pat and Krist and I had sat down in a room and written a song from scratch and jammed it out like Nirvana used to do. That was the first time that had really happened in 20-something years. Because Paul was there, we sort of forgot that. So the first couple of hours we were there, we were so focused and freaked out on Paul McCartney being in the same room that we forgot, like, 'Wait a minute, we used to be Nirvana, this is weird,' you know."
Foos drummer Taylor Hawkins described the session with McCartney for the new album, saying, "He hadn't even heard of the song. He comes in and Dave picked up an acoustic and showed him real quick. He sat on his special drum set that his tech set up for him. I sat there with a drumstick conducting. He did two takes."Grohl has still not revealed the identity of another secret star who sings on the album. He recently walked back his description of the person as the "biggest pop star in the world," telling Rolling Stone that the person "is, I think, more than that."He added, "This person's been around a long time. And I think I've met this person maybe a few times, but I'd never spent time with this person, and we had a blast together." He denied that the "person" was either Taylor Swift or Adele as rumored.In addition to McCartney, confirmed guests on the September 15th release include The Bird And The Bee’s Inara George, the Dead Weather's Allison Mosshart, saxophonist Dave Koz and singer Shawn Stockman of Boyz II Men fame.
