BubblyRat,

There's a reason that recording is so good. I bet it was one of the ones put out by Green Linnet, which was the actual record label for all those artists. Toward the end of their existence, Green Linnet decided to cash in on the Celtic Crap vogue by making compilations of their own artists and marketing them exactly like other companies marketed Celtic Crap. Only Green Linnet artists were the ones you mentioned, not crap at all! Clever, eh?
