Star Wars: The Force Awakens cast perform a cappella version of theme on Jimmy Fallon

Who knew these guys were so musical?

The cast of Star Wars: The Force Awakens teamed up for The Tonight Show with Jimmy Fallon to perform a medley of the franchise's most iconic themes. 

Starting off with Fallon himself, and the show's house band The Roots, things kicked off with John Williams' classic "Main Title"; they were soon joined by Daisy Ridley (who plays Rey), John Boyega (Finn), and Oscar Isaac (Poe Dameron). Adam Driver, the man behind The Force Awakens' highly anticipated villain Kylo Ren, then steps in for Darth Vader's own iconic theme "The Imperial March"; he's then joined by another of the film's primary antagonists, Gwendoline Christie, who plays Captain Phasma. 

Then, time to switch things up: Chewbacca, C-3PO, and new droid BB-8 take on A New Hope's Cantina Band. The Force Awakens has been reported to feature its own cantina song, though Williams declined to pen the track; leading director J.J. Abrams to call on the creator of Broadway hit Hamilton, Lin-Manuel Miranda. Will Miranda be able to top one of the catchiest tracks in cinematic history? 

For the finale, Lupita Nyong'o, Carrie Fisher, and (surprise treat) Harrison Ford joined the rest of the cast to round up the end of the film's main theme.

Star Wars: The Force Awakens hits UK theatres 17 December.
