Yeah, you must be joking!
I agree to 100% that "What happened to your voice in 72, Robert?" is on the very top of the list. But sadly only in theory. I bet that his ego would NEVER EVER allow this question. Past, present or future: He would book this question as "Injury to his Majesty, Robert Anthony 1." Honestly, he turns 69 this year & still thinks he has the veto right to put down the cronological live album, a hearfelt wish of Jimmy since the 70ies! Jimmy, the man he owes more to than anyone else!!!- and he doesn`t give a shit. He had the guts to strut the stage 73 to 75, doing his Golden God thing, head full of snow, groupies and all that jazz, while his voice was shot at 75% of the shows. Why is he acting like a miffed old maid? We all know, that Jimmy would surely pick great shows with Robert in marvelous voice, why worry?
What happened to his voice in 72? Alcohol, cocaine (of course C. can damage a voice by damaging the nose & the paranasal sinuses causing a gridlocked nose), too many late nights & his unnecessarily shrieking in the early days due to his insecurity & too much cigarettes........
He did not only lose his high range by Oct. 72, the warmth tone of his low range was gone, adding the sound of a locked nose on top of that.
His natural voice was a God-given gift, he treated so thoughtlessly. What a shame.
