Interesting, but no reference to Shirley's 1959 recording and, to my ears, June's melody is based on the Shirley Collins one. Shirley only sings four verses and the first three are virtually the same as June's verses 2,3, and 4. The Bellowhead version acknowledges that it came from Shirley, although they turn the first verse into a chorus. I've noticed other instances of recent recordings where there's an obvious debt to Shirley, e.g. Jim Moray's Gilderoy on his second album. (And some on his Sweet England album!)
