No, the alt rockers didn't PLAY a Kiss song as they kicked off their concert tour in Austin, Texas last night.
They took a fan with full Kiss make-up out of the crowd and brought him on stage for a song.
Foo Fighters' leader Dave Grohl handed him a guitar, labelled him "Kiss Guy" and let him play "Monkey Wrench" with the band.
Will this practice of bringing fans on stage eventually backfire and result in some sort of problem?
