Billy Dee, Patton Oswalt do 'Star Wars' karaoke

This week another Course of the Force kicked off to celebrate Star Wars and raise money for charity.

The light-saber relay travels through California to San Diego in the days before Comic-Con. To help promote it, a great Star Wars karaoke video has popped up — and among its guest stars is Lando Calrissian himself, Billy Dee Williams.

Enjoy Billy Dee, Patton Oswalt, Chris Hardwick and others sing Coconut Records' West Coast. (Actor/Coconut Records musician Jason Schwartzman even makes a cameo.)

A "making of" video is coming soon, and you can download the song via Soundcloud. To learn more about Course of the Force, head to courseoftheforce.starwars.com and Twitter.
