Jimmy Fallon had members of the Star Wars: The Force Awakens cast on The Tonight Show last night and, as you know, you can never just be a “guest” on his show. You have to take part in a sketch that has to go viral. So Fallon recruited the members of the film’s cast for an a capella rendition of John Williams’ Star Wars themes.

The members of the cast that were on Fallon were John Boyega, Daisy Ridley, Oscar Isaac, Adam Driver, Gwendoline Christie, Lupita Nyong'o, Carrie Fisher and Harrison Ford. Yes, even Ford took part in the a capella performance with The Roots.

Fallon’s Brady Bunch-esque a capella performances have been a part of the show for awhile. Here’s the “We Are The Champions” one he did after the Super Bowl.

And here’s “We Can’t Stop” with Miley Cyrus.
