Jimmy Fallon and The Roots are doing their a capella thing again, this time with a very crisp rendition of Star Wars' best-known film scores, in time for Star Wars: The Force Awakens.
They've roped in the film's cast members for the medley, and even BB-8 and R2-D2 make an appearance. Adam Driver, who plays Kylo Ren in the new movie, leads a particularly rousing segment of Darth Vader's theme, "The Imperial March."
