/////josepp: "////When it comes to folk music, most American folk music has British Island roots..."

There might be a few Celts who would take issue with that!!!

The Celts are British Islanders too; it's the way it works over here in terms of the various contrivances of disparate national / regional identity and the historical provenance thereof. One would, in any case, have thought the most objection to the statement that most American folk music has British Island roots would come from the Africans.
