Among the many things that make the Foo Fighters such legends is the fact that they've made a name for themselves for busting out surprise guests during their live performances. Just recently, Dave Grohl made some serious waves by inviting a random fan on stage during a gig in Rio de Janeiro, who went on to kill it on lead guitar for a fired-up rendition of 'Monkey Wrench'. Now, the Foos have pulled another strange cameo stunt.

As the rock giants performed in Jacksonville, Florida, they were joined by Travolta during a cover of ‘You’re The One That I Want’ from the soundtrack of one of Travolta greatest hits, 'Grease', reports NME.

Travolta, who recently wrapped up filming the Fred Durst-directed film 'Moose', apparently watched Foo Fighters’ set from the side of the stage. About mid-way through the performance, the band covered Travolta and Olivia-Newton John’s Grease classic, “You’re the One That I Want”, and Travolta briefly appeared on stage to give Grohl a hug.

Footage recorded by fans sees Dave Grohl cryptically teasing that “it gets better” during the start of the performance before the Hollywood icon makes his appearance on stage.

His arrival prompts huge disbelief from fans, and he’s seen having a brief chat with Dave Grohl before he salutes the crowd and dances off stage.

“It’s too much! Thank you and good night”, Grohl remarks of Travolta’s appearance — before making his mock exit from the stage.

Travolta's cameo wasn't the only surprise of the night. Earlier in the night, during the same set, Foo Fighters brought out the one and only Billy Idol to cover John Lennon’s 'Gimme Some Truth'.
