In my Aleister Crowley research I was stumbling on some references which led me to others and finally to this post.
These women all were the muses/girlfriends of famous musicians and all of them were blondes involved in Aleister Crowley's OTO or the Process Church (English version of the Church of Satan) and friends of Kenneth Anger.
Anita Pallenberg, dated Brian Jones and then Keith Richards, also slept with Mick Jagger--self-avowed witch. Was also in Barbarella. Several mysterious deaths occurred around her.
Marianne Faithful, dated John Dunbar, but was best known for being a recording artist and dating Mick Jagger. Because of her he wrote "Sympathy for the Devil" and "You can't always get what you want". Was a member of the Process Church.
Both Marianne and Anita were friends with Bobby Beausoleil (of Charles Manson fame)
Patti Boyd who was married to George Harrison, Eric Clapton (who was the subject of Eric Clapton's Layla), and also had sexy times with Ron Wood.
Patti was friends with Kenneth Anger, Sharon Tate (of the Tate murders) and a devotee of the TM movement.
Pamela Debarres was the girlfriend of Mick Jagger (briefly), Michael DeBarres, Alice Cooper, and other rock stars, but is most well known for being the long-time "groupie"/girlfriend of magical guitarist and Crowley devotee Jimmy $#@!ing Page who also was tapped by Kenneth Anger to do the soundtrack for Lucifer Rising
