Putnam, a bass guitarist and member of the renowned Muscle Shoals rhythm section, played on 120 Presley songs. He recalls how much energy Presley displayed during the marathon recording sessions that ran all night at RCA Studio B in Nashville in 1970.
“Elvis could focus better than any artist I ever worked with,” Putnam said. “He would learn a new song in five to 10 minutes, and was ready to deliver a killer vocal on the first take. That was very unusual.”
