Carolos Santana, he wrote a book about his life, I read it, a good read, bought it at the "Dollar Tree".
Recently bought a book a lady wrote, who dated Ray Charlse, it's called, "Ray & Me", she lives in Missouri.
I have yet to read it.

My sister told me about an hour ago that he fainted on stage from exhaustion or some other reason I'm not sure I got to look into it. But then she also told me that some kind of seer recently predicted this would happen, and shortly after that he would die. The Seer didn't produce a name, just that it would be a big musical star.
