I may get flamed for this, but it's important to state my opinion. Robert mentioned that he caught flu in, I think, 1972. He points to this event as the reason for the decline in his voice. I'm here to state that he lost his voice because he put the pedal to the metal for so long that he just blew his voice out. Smoking, drinking, cocaine, staying up for far too long repeatedly will destroy your voice. I don't believe he ever went to a vocal coach so he could learn to sing without straining his voice. When someone like Axl Rose's voice suffers from abuse I conclude the oik deserves it. But all I've ever heard of Robert is that he's a gentleman to his fans.
