I disagree.
Elvis wasn't as much about his ego as most people may think.
He humbled himself by "dying" in the bathroom and then was reborn under a new identity where he was whisked away (by a helicopter that landed in the back of Graceland) to a private Hawaiian island where only Hawaiians are allowed. After a couple of years Elvis was rested and moved off to Germany for a year and he was spotted more than a few times.
One of the tabloids ran a piece in the mid 80's with the headline of "Is Elvis Impersonating himself?" and they had a picture of Elvis impersonating himself. A ton of people speculated that the face of Elvis was superimposed and a beard added but sure enough it was him. They almost caught the guy more than once.
But thankfully he lived a good long life.
These are the facts as I know them.
