The harmony is strong with the "Star Wars: The Force Awakens" cast!
In a video unveiled on Tuesday's "The Tonight Show," host Jimmy Fallon led an a cappella medley of composer John Williams' most memorable music from the blockbuster franchise – with the help of a few special guests.
Presented within an expanding, multi-colored splitscreen, the clip first features newcomers Daisy Ridley and John Boyega teaming up with Jimmy and The Roots for the iconic "Main Title" theme, with assistance from co-star Oscar Isaac.
Onscreen villains Adam Driver and Gwendoline Christie represent the Dark Side with a rendition of Darth Vader's ominous "Imperial March," as a cavalry of familiar-looking Stormtroopers provide backing vocals.
The fun kicks into high gear when Lupita Nyong'o appears with series icons R2-D2, C-3PO, Chewbacca and early "Force Awakens" favorite BB-8 for the lively "Cantina Band" number, before Carrie Fisher and even Harrison Ford join the entire gang for a sweeping grand finale.
Noticeably absent from the performance is Mark Hamill, whose hero Luke Skywalker has been kept in the shadows from most of the film's promotional material.
"Star Wars: The Force Awakens" hits theaters nationwide on Friday.
