I've also had dinner with him (and some of his friends) once - at the Pork Store Cafe on 16th Street - and there he was quite pleasant. Afterwards, a few of us went to his place nearby on Guerrero and that's how I know where he lived.
He died from complications of AIDS.
He has a Wikipedia page which is worth reading.

Anyway, those are the memories that came to mind as I walked by where he used to live.
