Johnny Hawksworth has been played on NTS shows including Jonny Trunk Plays God, with Jazz Rule first played on 15 February 2013.

Johnny Hawksworth (1924–2009) was a British musician and composer who lived and worked in Australia since 1984.

Hawksworth initially trained as a pianist, but also played double bass for the Ted Heath Band during the early 1950s and through the 1960s. He is probably best known, however, for his short compositions for television. These include Salute to Thames (the famous identity tune for Thames Television) and also the theme tunes for the 1970s series Roobarb, George and Mildred and Man About the House. He also contributed some of the incidental music used in the 1967 Spider-Man cartoon. (Although originating from the United States, Spider-Man had most of its incidental music supplied by British composers, including Phil Coulter, Syd Dale, Alan Hawkshaw, David Lindup, Bill Martin and Johnny Pearson.)

Hawksworth has also written many pieces of stock music for the De Wolfe Music library. He also provided the hypnotic musical soundtrack to Geoffrey Jones' classic British Transport Film "Snow" (1963).
