KISS’ Gene Simmons Tips Dave Grohl as Foo Fighters Welcome Him Onstage in Vegas: Watch

Foo Fighters surprised the crowd at their show a few nights ago in Las Vegas, bringing none other than KISS singer-bassist Gene Simmons out onstage.

Video footage of the concert shows Foo Fighters frontman Dave Grohl telling a fan in the audience that his KISS makeup doesn’t quite cut it: “I don’t think that [looks like] Gene. I think that’s like corpse paint. I’m not sure what that is.”

Grohl then does a brief impersonation of Simmons, before guitarist Chris Shiflett starts playing the riff to KISS’ “Calling Dr. Love,” with drummer Taylor Hawkins soon adding the beat. “We can’t do that in front of Gene Simmons,” declared Grohl, who motioned to the side of the stage and said, “Gene, you can at least come out and show ’em your punim [Yiddish for ‘face’].”
