A partial answer to one of your questions: Here is a book review by Ronald Hutton which distinguishes three forms of modern paganism:
"One is American feminist witchcraft, based upon the idea that the witch figure and its divine complement, the Goddess, can be evoked by any woman bent upon personal liberation. The second is Wicca, a mystery religion developed in England and based upon a rigorous process of training and initiation and a cosmos polarized between equal female and male forces. The third is hedge witchcraft, the modern version of cunning folk, featured here in its commercialized form of individual practitioners offering occult services for money." (These words occur a few paragraphs down the page).
The old words to Nonesuch, which I mentioned earlier, are titled "The French Report" in the Baltimore Consort's album "A Trip to Kilburn". Another name for the tune is A la mode de France, which words form a sort of refrain in the lyric. The words seem to be an anti-Cromwellian political comment.
