I don't think Elvis had any idea how bad his finances were but if he did he would have fired all those guys that were laying around on his couches waiting for handouts! And, he probably would have sold Billy's doublewide to recoup some of his money!!
There is no way that Elvis was not concerned about the welfare of his one and only child.
Has anyone ever heard about the life insurance policy he had through Lloyds of London that was never cashed?
