Here is Elvis author and expert joe Tunzi's thoughts on unused footage from EOT and what may or may not be still hidden or unreleased as far as concert footage:
QUESTION- Do you think that the unreleased filmed shows for “Elvis On Tour” in Richmond, Macon and Charlotte will ever be released? This is a crying shame that nearly 30 years since the sad passing of Elvis we still haven’t got what Elvis probably thought would be out to the fans.
Joe Tunzi: The footage from many of the cities on the April ‘72 tour was done strictly on assignment, whereas someone from the production of the film was sent with a camera to film something the producer was looking for, whether that be something as mundane as a city limits sign along the highway, interviewing a local mayor in Roanoke, entering the stage or leaving the stage, Elvis dropping down on one knee or even holding up a pair of women’s panties while on stage. A prime example of this is the sign outside the T.H. Barton Coliseum in Little Rock, Arkansas was shot but the entire show wasn’t shot. These clips were added to the shows where a good majority of the show was filmed and recorded (Hampton Roads, Richmond, Greensboro and San Antonio) to fully illustrate a sense of Elvis going from city to city.......
So perhaps the only shot from some of these concerts was just what you see in EOT.....whatever the producer had assigned for that nights taping.
