Hi Jennifer!
I saw your message in the Soul Train article, looking for a video. Your best bet is Youtube, it's where I get all the details of all the episodes that I update in wikipedia. Even if you can't find the right episode, there are some 3-4 users that upload most of the episodes, with a bit of luck you can contact them and maybe they'll have the specific episode you want. On another note, I envy you for being part of Soul Train. I only learned about it a few years ago, it's an awesome TV show! With wonderful dancers, I'm sure you're wonderful too. ^_^
