Re: Alice's post. I have a notion that Western music is different from other types in distribution and boundaries. Notably, that the border between Alberta and the states to the south is pretty culturally porous, and always has been. Ian Tyson is once again my example--even though he's a Canadian icon, he's even more a western artist in a biogeographical way that makes the national border irrelevant.

Doesn't surprise me that fiddle tunes would be similarly shared. There's a lot of similarity between New England and Ontario fiddle & accompaniment styles too.
