SUCH helpful replies. Wow, thanks so much to all of you. I'm thrilled.

Khanjar, I love "Go with it and blunder through." That's kinda my plan.

Kashmir, it was supposed to be a beginner's class, but most people were on their second and third times taking the class, and I think I'm the only beginner. But as you said, there's warmup and technique and only the last quarter is devoted to the choreography.

Jenc, you said, "Think about moving a spot just above your pubic bone pulling and pushing with the muscles around instead of using the legs." It's gonna be a while before that even makes sense to my confused body, but I'm thrilled to hear you're up there with me in age (and knee troubles) and still enjoying the dance!

Thanks again, you guys!
