Foo Fighters performed at the Welcome To Rockville music festival last night in Jacksonville, and they brought out a very special guest in the form of John Travolta. Travolta was apparently in town filming for the new Fred Durst-directed movie Moose, which he stars in as the titular character. The actor was standing side stage and came out for a wave as the Foo Fighters covered the perennial Grease hit "You're The One That I Want." Watch footage of them together below.
