Legend of the Witches (1970) 
A slice of Wyrd... part '
nature' film, part very serious (po-faced???) essay about witchcraft and occult rituals. Equal opportunity nudity abound, willies and boobs flapping about everywhere
I think that the occult rituals have been re-enacted by actors, i'm very dubious that any coven would be populated by so many young, slim, good looking lads and lasses
Some fantastic imagery here, nice creepy music score too, just a bit of a weird
man in a white coat "I'm a qualified scientist" commentary!
An interesting curiosity
Rated X in its day!!
