The aca-amazing Force is strong with these ones. Obviously, with all of the promotion for "Star Wars: The Force Awakens," what we've really been waiting for is a "Brady Bunch"-level a cappella "Star Wars" sing-along with the full cast, Jimmy Fallon, and "The Tonight Show" band, The Roots.

Here's the main "Star Wars" cast -- including Daisy Ridley, John Boyega , Oscar Isaac , Lupita Nyong'o, Adam Driver, Gwendoline Christie, Carrie Fisher, and even Harrison Ford -- performing their little "buh-buh-buh-BAAHHHH-buh" parts together. Adam gets a great solo with the "Imperial March" (followed by Gwendoline). And you have to love The Roots as Stormtroopers, then rocking out to "The Cantina Song" as Chewie looks on in confusion.


It's awesome, but the question remains -- WHERE'S MARK HAMILLl? What have they done with Luke Skywalker?! Only a few more days until we can find out.
