He truly was the King. He comes from a era of musicians that actually had to be able to carry a tune. Nowadays there are computers and vocal synthesizers that hide the fact that they can't sing.
My mom cried too. My family was watching tv when the breaking news of his death came across. You would've thought her brother died. I have to admit, he was a great singer and enjoy listening to his music even today..
Something that gets lost in conversation with the King is his character. How many of todays singers with Elvis' status would honor their draft card and go fight in a war like Elvis did? One of a kind.
