Thanks, Brian, for the added info. I somehow--don't know how--had the feeling it was from Ulster. An obviously misleading feeling. And I hadn't even thought of the tempo as a stylistic consideration. Duh.

I'm working it up to sing at the concert at the Silver Falls folk music retreat (at Silver Falls State Park, Oregon) put on by the Corvallis folk. It's wonderful weekend of music, singing, and dancing in the old growth hills of Oregon.
