"In Elvis, you had the whole lot; it's all there in that elastic voice and body. As he changed shape, so did the world. His last performances showcase a voice even bigger than his gut, where you cry real tears as the music messiah sings his tired heart out, turning casino into temple. I think the Vegas period is underrated. I find it the most emotional. By that point Elvis was clearly not in control of his own life, and there is this incredible pathos. The big opera voice of the later years -- that's the one that really hurts me."
