Elvis At Life's End

This is a video I made a few months ago initially as a rebuke to one very mean-spirited video someone had put on YouTube trying to make out Elvis was drunk onstage.

But then I decided to make the video a little bigger and show how Elvis' artistry was intact right to the very end!
One of the biggest mysteries of the whole CBS contract was why on earth they filmed nothing from Indianapolis. It was the finest show of this tour and quite possibly Elvis' greatest show since Pittsburgh New Years' Eve!
Also I have always wondered why they had the cameras set up outside the Pershing Auditorium on 20th June 1977 to film the ELVIS- KING OF ENTERTAINMENT sign, but then not bother to film anything of the actual concert?
