I don’t follow why you need to be so secretive, here’s a link to the speculations of someone whose articles aren’t welcome on FR, but it’s not as if we are totally in the dark, Brown Deer posted a link to what this person speculated, here, quite some time ago:

And as that unmentionable author’s site requires subscription, here’s a link to a reprint:

Hardly an item to get all we wee’d up about:
“...And throughout the 1960’s, with interest in Eastern philosophies and religions reaching their peak, numerous rock stars of the day took an interest in Subud, including members of the Association, the Byrds, the Beach Boys, the Mamas and the Papas and Crosby, Stills & Nash...”
Not posting links because the content might disappear used to be what did a long time ago, until I realized that posting on FR was the best way to keep the material accessable.
