Poppagator: sorry,I only threw the Denis McGee and Doug Kershaw in as a diversionary joke, it was quite clear you you were talking about Breton Celticism. But I would seriously query your argument about the cajuns keeping essentially separate from the rest of the world. I think you have completely overlooked the major influence on cajun music. I think if you take a cool look at Canadian French music, French French music, and Louisiana French(cajun) music, and consider the similarities and differences, you will come to exactly the same conclusion as virtually everyone else who has studied this. Which is: that the main roots of cajun music are black. Surely the significantly interesting thing about cajun music is not its Celticism, but the fact that black and white music integrated to a remarkable degree in rural Louisiana, in marked contrast to what happened in other parts of southern USA. (I only refer to music, I am not discussing to social and sexual interactions, that is another whole area of research).
