WATCH: John Travolta Join Foo Fighters On Stage As They Perform A Grease Classic

Grease star John Travolta has joined Foo Fighters on stage at Rockville Festival.

The Hollywood star was watching the Foo Fighters from side of stage when the band busting into the Grease classic ‘You’re The One That I Want’ with Dave Grohl shouting to Travolta; “this one’s for you”.

Travolta waltzed onto the stage, as if in character and danced off the stage as the band continued to play.

The set was star studded, with festival highlight Billy Idol also making an appearance on stage with the Fooies.

What a show!
