Manson with Dennis relationship above
Brian Wilson mention here
In 2006, in an interview (link is external) with Goldmine magazine, McGuinn was asked about his involvement in Subud. Here is what he said:
“ I had been flirting with it from The Village. I got interested in it in New York and sorta followed through in L.A. By 1967 I was into it. By ’67 I was into it whole hog. Legally, I only changed my middle name. My first name is still James. If someone wrote a check to Jim McGuinn, I could still cash it (laughs). I switched my middle name. It was Joseph, and I switched it to Roger. And started using Roger as a first name. There was a Subud house in downtown L.A. on Hope Street, and The Beach Boys used to hang out there. I remember that. Then, Brian (Wilson) formed his own chapter at his house during his ‘sandbox’ phase.” -
