Okay, there's a clip of Bertrand Deraspe here playing with a group of well-dressed French-Canadians. My download is so slow that I can't really say anything much about what he plays on fiddle - he starts off on guitar and switches to fiddle in the middle of the clip, which is the point which I have just reached. It's sort of a "train song"; maybe he goes into Orange Blossom Special. Anyway, there are a few other clips listed; looks like he might play some more straight-ahead stuff in one or two of them.
