Dave Grohl kicked off the Foo Fighters’ latest U.S. tour last night in classic style when he invited a Kiss fan — complete in band makeup — from the audience onto the stage to perform “Monkey Wrench.” You can watch the moment below, along with other clips from the concert in Austin.

“You ever done this before? It’s really fine,” Grohl told the fan, who was given the name “Kiss Guy” when he was too blown away to identify himself properly. Handing him his guitar, Grohl then told the crowd, “He brought his own fucking pick!” As the band broke into the song, Grohl appeared more likely to mess up than Kiss Guy, who made the most of his moment in the limelight. After spending much of the song exchanging expressions of amazement with his bandmates, the frontman ended the guest spot with an astonished, “Holy shit!” MORE
