After riding the skimmer to Ulence Flats in Space Quest I, you'll come across a small drinking establishment known as The Rocket Bar. While you don't really spend a huge portion of the game at this location what I loved about it were the "live acts" on stage playing pretty awesome music. Not only that but there would be one of three potential acts on the stage and they are all parodies of real groups/artists. This one comes from the group that look suspiciously like the Blues Brothers, but you could probably tell just by listening to it :).
Special thanks to Quest Studios for making these tracks available for all Sierra fans to enjoy.
