Sorry Dee, I was really tired last night and instead of sleeping, I sat up eating cake and surfing the internet. (Some behaviors still need changing!) Your post slipped by me.
I thought Frank Zappa never used. I mean he was a teetotaler from birth. All the interviews I saw with him and bios stated he was anti drugs and alcohol, though a heavy caffeine user. Of course that constitutes him as sober, just not recovering
Does Keith still drink? I'm sure I heard Charlie say in an interview they've pretty much all had to make the drinking in due to health concerns as they got older.
