Video Link. This horrible, blurry mashup of Spock lipsynching to the Bad Brains is hilarious if you grew up on DC hardcore, otherwise just skip this post.
Here's the Bad Brains performing the song live in 1982. They were one of the first bands I ever saw live, and they changed my life and defined punk rock for me. These equally-shitty quality YouTube uploads might give you an idea why: 1, 2, 3, 4, 5. Just pure, crazy speed. (thanks, Sean Bonner)
Update: To all the humorless pedants in the hizzouse who like to use email: yes, this is an unauthorized adaptation of "Bilbo Baggins."
