Dave Grohl talked to ET Canada and revealed yet another big name to appear on the upcoming Foo Fighters album, Concrete and Gold. It’s Paul McCartney.

Oh, and that’s apparently not the biggest name on the album.

Grohl tells ET Canada:

“Paul McCartney plays drums on one of our songs. 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 said.

“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.”
