Great question you put up here!
I think Elvis had a lot to life for, his daughter was at graceland at that time, we all know how much he loved her and he didn't want to see that Lisa was hurt in anyway, so way kill yourself with Lisa around?
And didn't he tell a lot of his buddies that he was going to do the best tour he ever did? To prove everyone wrong about his appearance ect.
And why -if he wanted to kill himself- did he played racketball that evening and played some songs on the piano?
So there were no such plans for killing himself.
All those stupid facts that were showed in that show, were based on almost nothing, only to fill a 1 hour show.
We all know that Elvis wasn't in top shape in june 1977, but there are some pictures going around from august 1977, that are showing a trimmed down Elvis, his face isn't that blown up anymore, his complete body was showing a more normal shape.
The only reason for all those medications, that i can think of, is that he wanted to take those for one last time, and from that point on no more drugs. But that we will never know, cause that package of drugs was 1 to many. And please remember that he had 3 heartattacks allready, wich he didn't know, cause of all those pills he took, he didn't feel a thing with all those pills anymore. If there was just 1 person who could tell him the truth about those **** pills..maybe he would be still here...if ..if...if..
I think we never find out the truth about that...but for sure he didn't kill himself!
He even planned a gospel tour for the new tours in 1978..according to Charlie Hodge. He also told in his video -the elvis i knew- that elvis had cancer, bonecancer to be exact. That Elvis found that out only a few weeks before his death, and Charlie was the only person who Elvis told that to. And that Elvis told him not to say a word to anyone about the cancer. And Charlie was a real close friend to Elvis, so i believe his story. For the persons who didn't see the video by Charlie Hodge, please try to get it, it's a amazing story that he is telling there.
