Jimmy Fallon, The Roots, and the cast of Force Awakens sing a Star Wars medley

Written by composer John Williams and performed by the London Symphony Orchestra, the soundtrack to the Star Wars saga exists one of the most recognizable pieces of music. No matter who you talk too — regardless if they've ever even seen a Star Wars movie or not — almost everyone recognizes that iconic intro. It's catchy, it's badass, and now it's been performed as an amazing a cappella medley by Jimmy Fallon (of The Tonight Show), The Roots, and several cast members of Star Wars: The Force Awakens — including John Boyega, Daisy Ridley, Adam Driver and, yes, even Harrison Ford. Missing, however, is Mark Hamill (Luke Skywalker) who has been noticably absent from just about all of The Force Awakens' marketing.
