I've visited Graceland twice and on both occasions what affected me were the homely details. The 70s toaster and microwave in the tiny kitchen. Elvis's private jet, the Lisa Marie, named after his daughter, parked near the house; at the back of the plane a double bed in which Elvis slept, presumably in a narcotised fug.
Ted Harrison, in his thorough examination of Elvis's cultural afterlife - The Death and Resurrection of Elvis Presley - points out that the Presley family might never have had to open their home to the public if the King hadn't died in what was, by rock'n'roll standards, penury. He was down to his last million, largely through the avarice of Colonel Tom Parker, his long-time manager.
As soon as he heard of his sole client's sudden death, Parker signed a hasty contract with Vernon Presley, Elvis's rather hopeless father, boasting: "I owned 50 per cent of Elvis while he was alive, and I own 50 per cent of him now he's dead."
A few years after Elvis's death, he had bled the estate dry.
Priscilla, Elvis's ex-wife, rode to the rescue, with what Harrison calls her "untutored flair" and "innate toughness". Graceland was opened to the public (the ground floor, not the upstairs where he had died in the bathroom). She seized control of Elvis's image and reined in the flourishing trade in Love Me Tender Dog Chunks and Elvis Sweat ("Elvis poured out his soul to you, so let his perspiration be your inspiration"). Images of Elvis that were disrespectful or showed him as overweight were banned.
