Dave Grohl and the rest of the Foo Fighters are taking up residence on the “Late Show with David Letterman” this week, and the band kicked off Monday night with a surprising choice: a four-guitar cover of Black Sabbath’s classic “War Pigs,” featuring country singer Zac Brown.

“Well there, you see, that’s what we’re talking about,” Letterman said.

“Zac Brown. Black Sabbath. Foo Fighters. I don’t know, what do you kids want from me?”
