So ... we're back to defining Celts as Irish and Scottish? No - I don't really want to stir, but ... {{sigh}}I've just finished reading Bill Malone's "Singing Cowboys and Musical Mountaineers". He certainly seems to want to deny the Celtic / C&W connection and I don't really think he puts forward enough evidence to prove his hypothesis. I do, though, think that people don't look at a broad enough spectrum when they're looking for the origins of American musical traditions.
Still, more power to your elbow and I hope the show is a 'hit'.
