Back to the matter of the RC clergy: just for the record, a number of priests have been front and centre in the 'revival' of Cape Breton fiddle and dance for the last fifty years. In Cape Breton and Prince Edward Island, at least, it is not unusual at all to see the local priest get up and give a step at a fiddling event, if he is not playing. While there are a few - not many - stories from earlier days of priests repressing fiddling from earlier days, it does not seem to have been a widely-enforced policy, as it apparently was in Ireland.

I never heard of any repression of fiddling on the part of the Presbyterian clergy in Cape Breton - but the playing of anything but religious music was proscribed on the Sabbath. Some say that that led to story-telling as opposed to fiddling becoming a particularly strong folk-art in the Protestant communities.

(All this is my impression from my direct experience, conversation, and a bit of reading, but no real research).
