I suggest contacting active dance troupes to inquire about the recorded music they use. Just Google for "French-Canadian dance troupe", then try "Acadian dance troupe". Lots of great hits!

One of my favourites (which I never get to see on the west coast) is the Acadian dance troupe La Baie en Joie, from Nova Scotia. They've been around for a long time and are very active, but they don't seem to have a dedicated home page.
