Here's some chapters that talk about Sandra Good from a book about her
sister called "Ginny Good."
I thought this was great:
"Sandy is a total hippie who was living with the Beach Boys in Malibu and now is with prospectors in the desert teaching Dean Martin's daughter how to lose her ego. They cluck their tongues about what bad shape Mia Farrow and Nanci Sinatra's heads are in, altho Miss Farrow gave away her clothes and is living ascetically, 'she just can't give up her image.' I would certainly like to see my sister after reading her letters. She hikes barefoot in the desert forever, and she used to deride my mystical propensities. She is an Aquarian—Pisces cusp—which goes right along with what she is now doing. An absolutely rebellious, unconventional mystic. I sort of envy her."
All I personally remember about Sandy is that she used to work as a sales clerk at the Emporium on Market Street. She sold scarves and plastic headbands and was a lot less charismatic than Ginny—less compelling, more drab. That was before she shaved herself bald, carved a swastika into her forehead and hung out with the rest of the Manson chicks chanting spooky stuff outside the Hall of Justice in L.A., and way before she and Squeaky set up their own website.
