I like the addition of interesting variants.If you want to order traditional Cape Breton fiddle tapes and CD's, try writing to the following and asking for a catalogue. They may be on the Web now so you might check. (And incidently, other than ordering CD's from them I have no connection with the following)
Breton Books and Tapes Cape Breton's Magazine Wreck Cove, Cape Breton Island Nova Scotia, Canada B0C 1HO
They have or used to have some pretty hard-core traditional stuff Scotty Fitzgerald, Mike MacDougall, re-releases of the old Celtic 78's and LP's, etc.
