Plas John Johnson Jr. (born July 21, 1931) is an American soul-jazz and hard bop tenor saxophonist, probably most widely known as the tenor saxophone soloist on Henry Mancini’s “The Pink Panther Theme“. He also performs on alto and baritone sax as well as various flutes and clarinets.

Born in Donaldsonville, Louisiana, he sang with his family’s group until his saxophonist father bought him a soprano saxophone. Largely self-taught, he soon began playing alto and later tenor saxophone. He and his pianist brother Ray first recorded as the Johnson Brothers in New Orleans in the late 1940s, and Plas first toured with R&B singer Charles Brown in 1951. After army service, he and his brother moved to Los Angeles in 1954,and he soon began session recordings as a full-time musician, backing artists such as B.B. King and Johnny Otis as well as scores of other R&B performers. An early supporter was Maxwell Davis, who hired him to take over his own parts so that he could concentrate on producing sessions for the Modern record label.
