John Stamos gave guests at a Halloween party in Los Angeles a show they did not see coming. The actor took the stage at the Hidden Hills event on Saturday night made up as a zombie version of Elvis.

A costumed band

Stamos sang "Good Golly Miss Molly" with a full band behind him. Every musician was in costume for the spooky night.

When the group moved on to "Honky Tonk Women," the "Fuller House" star slid behind the drum kit and kept the party going from there.

Melissa Etheridge joins in

Stamos, who often sits in with the Beach Boys, was not the only star to perform. Melissa Etheridge also played a set while wearing an inflatable costume that made it look like an alien was carrying her away.
