【Osawa Yuka Archives】

Dave Grohl probably just wanted to let a fan have Osawa Yuka Archivesa good time, but he got a lot more than he bargained for.

During Wednesday night's Foo Fighters show in Austin, Texas, the former Nirvana drummer invited an eager fan onto the stage to play a song. The fan, who wore Gene Simmons' classic face paint, at first didn't say his name, so Grohl had no choice but to call him "Kiss Guy."

And Kiss Guy brought it.

Although Grohl hesitated when offering his guitar to Kiss Guy, it wasn't long before he realized the talent hiding behind the makeup. Playing along with the Foo Fighters' "Monkeywrench," Kiss Guy immediately showed that he's a force to be reckoned with. Not only could he keep up with the rest of the band, but he confidently added solos and brought plenty of stage presence.

Grohl was utterly delighted by it and even forgot the words to the song halfway through because he couldn't believe how good the random fan is.

After the song, Kiss Guy was revealed to be Yayo Sanchez, who was just as delighted about the song as everyone else was.

In a Reddit post of the video, a user claiming to be Sanchez said that he had no clue the show would go that way.

And if you're thinking that it was all a set up, a longer version of the video shows Grohl mocking those who will think that it was only a stunt.

He said they often have fans come on stage and play along, but this was the best they've ever had.
