Four part harmony based on John Williams theme songs with lyrics all about Star Wars.  And it’s done by a one guy.

I can see a new Bud Light Salutes commercial now; Here’s to you A Capella John Williams Nerd Who Rips Off Moosebutter.  Yes, he really isn’t singing, but is lip synching to the group, Moosebutter.  Still, cool song, and nicely done.
