I read somewhere that someone had said he was diagnosed with schizophrenia at a young age. While of course I can't confirm this, it does make everything fall into place.

Well, people around the world are certainly mourning and celebrating his life at the same time, and although his music went right over my head I can see his incredible talent. mg
