Johnny Todd is an English Folk Song which may have originated in Liverpool, where it was sung by children to accompany skipping games. It was discovered by folk musicologist Frank Kidson and included in one of his collections of Folk Songs, though other versions of the song were also discovered in other parts of Britain and documented in other collections so its precise origins are uncertain. What is certain is that the song was known to Fritz Spiegl (1926-2003) and his first wife Bridget Fry, who together arranged the melody as the theme for "Z-Cars", a long-running BBC television police drama which started in 1962 and was set near Liverpool. Spiegl was born in Austria but left the country as a war refugee and later settled in Liverpool where he became principal flautist with the Royal Liverpool Philharmonic Orchestra. The Z-Cars Theme became very popular and recognisable to TV audiences in the 1960s and 1970s, and was frequently referenced on other entertainment shows. Fry and Spiegl also composed and arranged the themes for the follow-on TV series called "Softly Softly" and "Softly Softly: Task Force". The song Johnny Todd is also used as an anthem by the football club Everton and has been sung by fans of various other clubs.
