Thanks all for interesting info. I,ve been trying to obtain an LP with this tune on it, for yonks. I had it once but it got lost in lifes travels.It was sung by a touring group of actors & singers and I think the LP was headed Pryderi & his pigs, not to be confused with the similar named group from the States. I heard them first in Criccieth in a small hall in the main street in the early seventies. Anybody got any info on how and where I can get my hands again on this LP?
