Hmmm. I don't know about this one. I love John Lennon's work but I doubt I could have ever been friends with him. I don't know that I have ever not enjoyed someone's work because of their personal stuff. 'Course, most of the time I don't bother to learn about the personal stuff, because most of the time it just doesn't interest me. I guess I have never really thought about it. In the arts & entertainment fields in general, there are a lot of people over the centuries who have had personal problems, with substance abuse, mental illness, etc. I don't know why that seems to come with the territory.(There is a book called "Touched with Fire" that deals with the connection between creativity and mental illness.)

Mostly I guess I feel sorry for people with great promise who destroy themselves, or get destroyed by other means.
