Greatest Rock Vocal Ever?

Putting this into context, and remembering this was cut in 1957, and that the world had never heard anything like this before, this very well might be the best rock vocal ever. And perhaps the worst rock video ever. Life is funny like that. I can only imagine what the people around Elvis in the studio were thinking when this came out of his mouth. Goosebumps. That's what I get when I hear this.
