Dvorin met Elvis Presley through Colonel Tom Parker in 1955, and organized Presley's concert tours for the next 22 years. After Presley's death, Dvorin kept a low profile, attending Elvis conventions only after Parker's death.
Presley's Estate never gave Dvorin any royalties from his famous phrase, causing him to hold some animosity towards the organization.
Dvorin was killed in an automobile accident on his way home from a concert by Elvis impersonator Paul Casey. He and Elvis photographer Ed Bonja were driving from Palm Springs to Las Vegas when their vehicle swerved off the road. Bonja was treated at the hospital and released, but Dvorin was thrown from the car and died at the scene.
