Travolta joins Foo Fighters on stage for Grease cover

From Digital Spy

John Travolta has been dancing on a stage again, this time joining Dave Grohl and Foo Fighters on stage to revisit one of the most iconic moments of his career.

During a gig in New York, Grease star Travolta surprised fans by making an appearance on stage while Grohl performed 'You're The One That I Want', even making sure to bring out his famous dance moves for the key line: "It's electrifying!"

Foo Fighters shared a video of the moment on their official Twitter page, but thankfully the fans in the crowd managed to catch it at a better angle – and revealed that the actor didn't really fancy staying on stage for too long after his big moment.

Believe it or not, this isn't the first time Travolta has performed the song onstage with Foo Fighters, having previously surprised an audience in Florida with an appearance during the same song.

It's not the first time Travolta has even danced in front of an audience recently either, having followed up his Foo Fighters show appearance by getting up on stage to dance with 50 Cent at Cannes Film Festival in May too.

Earlier this year, the actor also weighed in on a popular Grease fan theory, which argues that pretty much the whole film takes place in the mind of a dying Sandy, who wasn't actually saved by Danny as she sings in 'Summer Nights'.

"I love it; imaginations are awesome," Travolta said about the theory. "These things are bound to happen to something timeless like this. It's so fun.

"I could have fun with it. But I know the writers of Grease, and I was around in the original days. I can't take it too far."

Travolta's latest film Gotti, about the late mobster John Gotti, is proving to be less well-loved than the '70s musical though, as it's been absolutely hammered by critics.

Gotti hasn't received a single positive review, meaning it's been slapped with a stinking 0% on Rotten Tomatoes, making it the actor's third film to have the dubious honour after Saturday Night Fever sequel Staying Alive and Look Who's Talking Now.
