I think what scared me most is that I did an internet search for you, and I could only come up with a few tapes, but the one Richard Simmons tape looked fun. I imagine I could really embarrass my teenagers with that one. But the idea of working out to Richard again after Cathe *shudders*
There is one called "Learn the Dances of the 70's" - it's instructional and not an exercise tape - don't know anything about it, but it mentions most of the dances I used to do. *dates herself*
Not much help, I know - sorry.
