I've run across a testimonial by a Christian pastor who was at one time deeply involved in the life of Timothy Leary, his movement and his family. He talks about that association in this video, and his being a part of their involvment with the Moody Blues. The Motion Picture Association would likely give this an "R" rating for graphic thematic content.
The relevant part starts at about 3:30
Also, here is a song by Oden Fong from one of his albums, which was released in 1979. I'm wondering what influences the Moodies might have had on his music, as orchestral strings are used in it. Or maybe a Mellotron? It seems to be more in line with folk rock.
