Have you been lucky enough to catch the Tonight Show Starring Jimmy Fallon sketch where they do the Brady Bunch–style collage of faces, but more colorful and set to a non-Brady song? Maybe you caught "We Are the Champions" after the Super Bowl," when One DirectionChristina AguileraSam SmithAriana Grande and Usher all joined in?

Tuesday night gave us a new edition, one where Fallon, the Roots and the cast of Star Wars: The Force Awakens a cappella'd their way through some of the most famous themes from a long time ago in that galaxy far, far away. 

We're not talking about a couple cast members, either. You've got new stars Daisy Ridley, John Boyega, Adam Driver, Oscar Isaac, Lupita Nyong'o and Gwendoline Christie, plus Carrie Fisher and Harrison Ford, who exchange a cute look at the end. #hanandleiaforever #iknow
