Because it wouldn't be a Foo Fighters show if something special didn't happen, OF COURSE the band had some guests over the weekend when they played Wantagh, New York.
After making a brief appearance at a show in April, John Travolta made a return to the Foo Fighters stage as the band played "You're the One that I Want" from Grease. While Travolta didn't do TOO much, he was clearly having fun again. Who knew he'd follow the band around?
But wait-that wasn't all. Why would it be? Red Hot Chili Peppers drummer Chad Smith also stopped by to take over drums for a cover of "Stay with Me" by Faces.
