I agree with the comment of Unchained Medley. I feel that this is Elvis saying goodbye to the fans. But I also feel that he got into the bounds of other music with that song. It feels more like Opera. Hitting high notes during that song and playing the piano. It feels that this isn't just Elvis that we have seen before. My opinion that version was the best. The others are great too but this version seem to be more powerful and meaning to it.
