Need something to get you ready for the premiere of 'Star Wars: The Force Awakens'?
Daisy Ridley, John Boyega, Oscar Isaac, Adam Driver, Gwendoline Christie, Lupita Nyong'o, Carrie Fisher and Harrison Ford all joined Jimmy Fallon and his house band The Roots for an epic acapella medley of the classic music from 'Star Wars', including The Imperial March and the Cantina Band song.
And they even got a few droids to join in!
