In two separate interviews, Billy Smith and Marty Lacker each spoke of the faking of Elvis' death....once regarding Elvis' plan to do so and once recounting that it was actually done.  These two interviews were done years apart.

Before I write one more word, I want it clearly understood that after the interview in the British publication THE PEOPLE, they have said "It was just a joke."  Below you will see this news article about the interview with both of them.  

Following the THE PEOPLE interview, you will see that they had also included their accounts of how Elvis was planning to fake his death and had discussed it with them...this when they worked with Alanna Nash on the book Elvis Aaron Presley...Revelations From The Memphis Mafia.  This book was published in 1995. 

Here we have THE PEOPLE article:
