This is one of the King's last concerts. It is rare footage from a doc called "This is Elvis". Subsequent copies I've viewed have had these sections cut out. A small part has been posted on the internet with disrespectful tags such as "Elvis Drunk".
This footage made me an Elvis fan. View it yourself and see what an truly human being Elvis was.
Elvis is asked some awkward questions about the Vietnam war. He reflects on the "image" of Elvis and real life. He turns the interview around with some funny observations.
