"Chicken Man" is a tune composed in 1975 by Alan Hawkshaw used in two popular British TV series since the 1970s.
Background
It was recorded in Munich as part of the Themes International music library. Hawkshaw composed the tune in less than an hour, claiming he "didn't really know what [he] was doing" and that "he just wanted to do something quirky".[1]
TV theme tune
It became known as the theme to the long-running children's series Grange Hill. In its original version it was used as the main title music from 1978 to 1987, and was replaced by a re-recorded version from 1988 to 1989. After being replaced by a completely different theme tune, it made a reappearance in the final series of Grange Hill in 2008. An entirely different arrangement of "Chicken Man" was also used as the theme to early series of the British quiz show Give Us a Clue, despite the fact that it was already being used on Grange Hill. It lasted as the theme tune from 1979 until 1981, when a new producer/director commissioned an entirely new theme tune.
