Some words we were definitely not expecting to type today: John Travolta – aka musical heartthrob Danny Zuko – joined Foo Fighters onstage in Jacksonville while the band were performing a Grease cover.
The rock titans were teasing the intro to You're The One That I Want (what an absolute tune, eh?) at Florida's Welcome To Rockville, when frontman Dave Grohl revealed: "It gets better!" and the actor strolled out onstage to a mind-blown audience.
While John Travolta's cameo didn't include any actual singing (boo), it was a pretty damn exciting appearance nonetheless – and it's kinda got us wanting a proper collaboration between them. It's been reported that John was in town to work with Limp Bizkit's Fred Durst on upcoming thriller Moose.
Just amazing.
