My mom was keen on Sabbath in her youth/young adulthood (and Hendrix, Cash and Stones, I think). She stopped listening to and never promoted Sabbath to my brother and me, when we were kids - because of the drugs and his antics.
When we were early teens, she basically told us what bad guys he and Cash and about everybody else who ever took drugs were ('cause drugs are bad, mmkay?).
When Dreamer came out, she couldn't help herself and started listening again, at least to some of the new, solo stuff. I don't know how long it lasted, and if she listened to old Sabbath again.
She was basically gushing over him and how great he was and so glad that he had that kind of a comeback.
I pressed her on the aforementioned matter, not just regarding him, but Cash as well (he had a renaissance with her, too).
She said "What else should I've said/done? But now you're out of the house and old enough, so I can listen to what I want again."
