Following up on whether JFK Jr. is alive, I have a personal experience with the related topic of whether Elvis staged his own death. In 1991 and 1992, actor/director Bill Bixby hosted a series of television shows titled The Elvis Files (1991) and The Elvis Conspiracy (1992). This was a time when TV programs abounded with 900 call-in numbers to query the TV audience for their input, and take their money because callers were charged a fee per call. I met Bill Bixby through my non-credited participation on those particular TV shows.
He had just acquired a home computer which included Prodigy and Compuserve consumer online services (like AOL, the first widely used internet portals with forum, BB and chat room features). He knew next to nothing about computer use, while I was an expert, so he asked me to teach him. Over the course of the next several months, I would meet with Bill at his Century City condo (next to Micheal Jackson) for computer lessons. On many nights, there was very little computer talk because he would much rather enjoy a fine dinner (prepared by his private chef), drinks, and talk. It was often a group event with his then wife, plus their assistant. Over that time he came to trust me with relating a number of Hollywood back stories. I do have personal pictures of some of those evenings, but have already shared them on social media, so I won't be posting them here. The accompanying collage is my way of verifying that Hwood period of my life, and a basis for the following.
The time I spent with Bill Bixby was just after his first Elvis Files show (August of 1991), and prior to the followup, The Elvis Conspiracy, which aired in January of 1992. One night, he was beside himself with excitement about the 2nd Elvis show in pre-production at the time. Someone (he wouldn't say who) called him a week ago, with a set of confidential photographs that he wanted Bill to see. He had just been handed those photographs.
Now, as a pretext, at that time I didn't have an opinion one way or the other, or care whether Elvis was dead or alive. Most of my time spent with Bill was just shmoozing. He was a significant Hwood friend/connection to have. Careers in Hwood are often built that way. I also knew the name of the game with those TV specials - they were intended to make money off the 900 calls from viewers. Some of those 900 shows back then were very shady and exploitative, while many had a legitimate product or service. Any show based on whether Elvis was dead or alive was certainly right on that line of exploitation. As Bill explained in the linked LA Times article, he had long been a friend of Elvis, and if anyone was qualified to host a show on that topic, it was Bill. He also did it to ensure that the show was not exploitative by presenting all the facts and theories in straight forward manner, with witnesses and experts, then letting the viewers draw their own conclusions.
