Steve, I spent the weekend at a dance seminar that Jerry Duke also attended. I took the opportunity to ask him about this. His initial response was that he didn't think there is a link. Then he started talking about how the development of the dance in New York was related to certain people's reactions to this rhythm (insert demonstration here) and the perceived need to sanitize it to this rhythm (next demonstration). It took only about 3 seconds for it to go completely over my head (particularly since at that point I had consumed <CENSORED> glasses of wine), but my conclusion was that he has thought about this very question and has some theories. I mentioned your name to him, so if you do decide to approach him, it won't be a complete surprise (of course, I have no idea how many glasses of wine HE had consumed at that point, so he might not remember ...). Let me know how the research is progressing ...
