Yeah, my favorite TV show of all time. I taped the full run when they were rerun on BET and am in the process of transferring them to DVD.
Here are the opening credits, with a very familiar gent singing a very familiar song.
The more I read about the show, the more it sounds like it was about 15-20 years ahead of its time...would've been right at home on HBO or some such in the last few years as a cable-network program.
EDIT: music-rights issues again re: DVD release, according to quotes posted at Wikipedia:
