Carolyn Hester recorded " The Dowie Dens of Yarrow" on her famous Columbia album ( 1962? ); the one where Dylan played harmonica - but not on the "Yarrow" track. Hester's influence in Britain in the mid-sixties was quite substantial. In the folk club I regularly visited back then, at least half a dozen songs from the afore mentioned album by Carolyn where part of the club's basic repetoire - and bet that situation was repeated nationally.
