John Travolta Joins Foo Fighters Onstage for Grease Performance [VIDEO]

 

The Foo Fighters' show got a little Grease-y when Danny Zuko himself, John Travolta, walked onstage as Dave Grohl sang the opening verse to "You're the One That I Want."

 

Earlier in the show, Billy Idol joined the band for Generation X's cover of John Lennon’s "Gimme Some Truth."
