Having been born well after Elvis had passed on, I understood him and who he was only through cultural cliches and static images. Having dabbled since my birth in a sincere interest in Elvis, I found this clip refreshing. It has given a new life to my understanding of Elvis. For a person that has by and large been reduced to a name, a voice, and a jumpsuit by those who aren't "Elvis people", Elvis was so much more and I think his rendition of "Unchained Melody", including his exit, shows just this.
Notice the fleshy microphone stand.
