Grammy-winning vocal group Pentatonix, which has roots in Arlington, took center stage at the American Music Awards on Sunday night to perform music from the Star Wars saga. You know, that old series of sci-fi movies that people have mostly forgotten and which nobody at all is talking about right now.

True to form, the group performed the classic music a cappella, though they were backed up by an orchestra performing John Williams' original music. The members of Pentatonix also dressed for the part, looking like they came from a galaxy far, far away. (Kirstin Maldonado was particularly recognizable rocking the Princess Leia buns.)

As they sang, music from both the original trilogy of films and the upcoming Star Wars: The Force Awakens played on the screens in the background.

The segment was introduced by Star Wars' own Han Solo, Harrison Ford. He also made a joke about how the theme song for Indiana Jones (another iconic character he played) sounds "vaguely familiar".
