His career was a testament to overcoming the odds and never giving up. First, there was his appearance. He did not have the classic "lead singer" look. But he had talent. And he made it big. Then, he lost his voice. I mean, lost it completely. He couldn't sing at all. Yet he overcame that as well, and returned to performing, once again making it big. Then, after collapsing on stage due to health complications, and having his insurance companies refuse to authorize full-length stage shows, he morphed his career again.
