The Foo Fighters were performing in Jacksonville on Sunday night. Fans got a surprise when Dave Grohl and the band, started playing a cover of “You’re the One That I Want” from the movie Grease. As the band started playing, John Travolta joined them on stage. He apparently had been watching the show from the wings. Unfortunately he did not join in on the singing.

Check out this fan video:
