Re: Beausoleil, what I read was that he was in Love early on, before they had that name; they were called the Green Leaves or something. They were just playing gigs, he never recorded w/ them. With David LaFlamme, he formed a free-jazz sort of world music rock band, and they did tape a few things. A version of one of these pieces ended up on Beautiful Day's 1st album (it's an instrumental piece). Bobby B. is quite a talented musician. From prison, he composed and recorded the (highly accomplished) score for Kenneth Anger's LUCIFER RISING film, replacing Jimmy Page, who worked on it previously.
It's a Beautiful Day was 60s progressive pop. Really nice production with violin. Sweet melodies. As an aside, Bobby Beausoleil (later a Manson associate and presently serving a life sentence) was in the band in their earlier days (he was also in Love with Arthur Lee).
didn't know about lee & hendrix. it's weird how many things get left out of "official histories."
