Bear in mind that, at the same time, the NeoPagan revival was taking off. Today Paganism has become respectable — or powerful — enough to be recognized by the IRS and the military, but back then it was wildly radical and, of course, denounced by the right-wing churches. Pagans had no use for the Christian devil, but were at least sympathetic to the iconoclastic rock songs. The first serious commercial album with blatantly Pagan songs was Jethro Tull’s “Songs from the Wood”, which has continued to sell steadily ever since. There is now a sizable body of openly Pagan music, readily available on the Net (particularly YouTube).
