I remember an interview of Michael's exwife Lisa Marie Presley where she said that's his real voice was not that high, that he used that voice as part of his persona, and Michael and her had had a conversation about how surprised the public would be to hear how deep his real voice was.
I have heard that his non-media voice was more like Joe's.
Yep. Came to a hall I went too in LA back in '83, as his own was staked out by reporters constantly. Much deeper.
