No, Elvis was in fact an 8th degree black belt.
Elvis Presley's hand-to-hand combat training in the Army sparked his interest in the martial arts. Elvis studied under Japanese karate instructor Murakami Tetsuji while stationed in Germany. Soon after returning to the United States, he tested for and earned the rank of first degree black belt!
Elvis Presley studied Shotokan under Juergen Seydal, Chito-ryu under Hank Slemansky, Pasaryu system under Master Kang Rhee, and the Kenpo style under Ed Parker.
Ed Parker was a tenth degree black belt, a senior grandmaster, and one of the premier martial arts teachers the world has ever known!
Elvis utilized his photographic memory to memorize the IKKA (Kenpo) manual, as written by Mr. Edmund K. Parker, Sr.
Elvis remained devoted to the martial arts, he achieved the rank of eighth degree black belt and his karate name was Tiger!
