Musical perfection! Star Wars: The Force Awakens stars Harrison Ford, Daisy Ridley, John Boyega, Oscar Isaac, Gwendoline Christie, Lupito Nyong'o and Carrie Fisher all teamed up with The Tonight Show's Jimmy Fallon for an amazing a cappella version of all our favorite Star Wars melodies!

Joining house band the Roots on Tuesday, December 15, the Star Wars legends added their voices to the best version we've ever heard of John Williams' now-iconic score  and the results have to be heard to be believed.

Of course, the Star Wars tunes don't have much in the way of lyrics  but that didn't stop the Hollywood A-listers from adding their totally vital "bah, bah" into the mix in this unforgettable musical bit.

The melodic extravaganza starts at "Main Theme," and weaves its way to "Cantina Band" via a little "Imperial March."

Watch the whole production in the clip above — and don't miss R2-D2, C-3PO, BB-8 and Chewie make their own (kind of melodic!) mark on the piece!
