@edgarblythe,
So, many years ago a friend and I were at a Los Angeles irish bar of some fame on a quiet afternoon and we ordered some brew. The other people there (2) engaged us, and turned out to be interesting, the guy, after some long time, at least an hour into the talk, way into other stories, telling us he'd been Hoffman's roommate. Rusty was his name.
Now, this stuff isn't new to me, as a woman friend claimed to be B. Streisand's early roommate, and in that case I believe her, longer story, more believable person.
What I remember him saying about Hoffman was that he was a slob.
snort.. that might have been true too.
