Presley actually recorded the song twice, the first time as part of his personal recordings while he was serving in the Army, then again for professional release in the 1970s, Vallis said.
“You can hear that he’s trying to emulate Sanford’s sound,” Vallis said. “You know, most people I know want to impersonate Elvis, and here Elvis was trying to impersonate him.”
Clark recorded several other songs in the 1950s and 1960s that saw minor success before he left the music business to work in construction, though he occasionally recorded in later decades on his own label, Desert Sun Records.
Sanford is survived by his wife, Marsha, and several children.
