The evidence is very compelling, especially the photograph of old Elvis with his grandson, which I assume is one of Lisa Marie's children. I actually compared that to a young elvis photograph. If you look around the eyebrows and the bridge of the nose, as well as the ball shape of his cheekbones, there's a definite resemblence, even after plastic surgery (perhaps the reason he says in one of his letters that he's unsatisfied with the plastic surgery job he got).
It makes you wonder, what did Elvis think of Lisa Marie and Michael Jackson? What did he think of Lisa Marie and Nicolas Cage? Did they break up because Elvis didn't approve? Has Nicolas Cage met Elvis?
True, there probably aren't dental records for his gold tooth removal. If you were a dentist, would YOU want that kind of record? No, they'd think you were nuttier than a payday candy bar. The dentist probably said let's just keep this little transaction to ourselves.
Dr. Hinton seems very honest and sincere, I mean he's a psychiatrist, he's worked hard to get where he is, do you think he would sacrifice potentially his license to practice psychiatry to write a book saying he thinks Elvis is alive? Dr. Hinton knew the right people, and he was in the right place at the right time. Elvis (Jesse) wanted to tell his fans the truth, and Dr. Hinton was his writer. Great job Dr. Hinton, write another one!
