Ken Knox's primary job was that of disc jockey for several Dallas, Texas, radio stations. During his brief movie career, which was a result of radio boss Gordon McLendon's inclusion of on-staff talent in his movies, Knox broadcasted on McLendon's KLIF-AM, the undisputed top station in the area at the time, from 1957-60. Later, he worked for easy listening stations including KTLC-FM (later KMEZ) in Dallas.
