Here us a legit question for everyone

If the Elvis estate can release all of these mid to late 70s concerts on the FTD label, why on earth can they not make an anniversary package for the Elvis in Concert special that aired on CBS in Oct of 77. I get the "answer" you would probably get from EPE, however some of these Concert Elvis was not in top format and some soulike they were recorded in a high school locker room. I've heard the unreleased footage from Rapid City, Omaha, and Souix City was way better than what was released but come on. It's still part of the legacy and therefore should get its proper due
