Ric,
Yes, the dance lesson is supposed to be replaced each month with a new one. I haven't been great lately about keeping up with a strict monthly schedule, but we're slowly getting better.
Next month we will have a brand new lesson on dance position. After that, I suspect we will have to re-run one of the old ones. Sooner or later, you'll see that Cuban Motion lesson again.
Sincerely,
