Just watched the Frank Zappa documentary by Bill S. Preston, esq.
It's phenomenal. Something of a hagiography, musically why not, since Frank was an incredible composer.
Warts-and-all doc about everything else. Example, Frank used to openly fuck groupies, his wife Gail knew. He even brought one home and she lived at the house, helped raise the kids.
An interviewer asked him about it, he says she got used to it. Also says he gets the clap, he tells Gail, she goes to get medicine for everyone.
"I like to get my rocks off like anyone. So I do what I do and she does what she does..."
