Scan Tester played EDELWEISS, so what, Why should i want to play it or hear it just because he played it.
whatever folk do in pubs or clubs, does not automatically make it folk music, and none of that justifies changing the name.
When I played yesterday on the concertina i did not call it folk music, when i played in a pop group and playedsmall faces sha la lee[ what dross], i did not call it folk music
