I used to know PVal in a distant sort of way - I worked at a bank in Arcadia in the early '90's and chatted with him regularly. It's been a lot of years but that was the peak of his career and he did not have "little man syndrome" - he was humble and kind with fans from my perspective (I was one).
Substance abuse shouldn't ever be tolerated. It's very sad that they didn't address it properly and with sincerity. Perhaps if they were more serious about it they could have actually helped him help himself.
