EPIC! 

Fans got a lot more than what they were expecting at this years Caljam Festival in California. 

During a Foo Fighters performance, Liam Gallagher came on stage for arguably the set's most "wow" moment, as they sang the Beatles' "Come Together" with Aerosmith's Joe Perry getting in on the fun. 

Gallagher gets fucking right into it and give a crowd surf a go.
