Young Soul Rebels

Caz's boyfriend in the film is the character "Billibud", a punk rock fan and voter of the Socialist Workers Party (a Trotskyist organization). Billibud is named after "Billy Budd", the title character of the novel "Billy Budd, Sailor" (written 1888, published 1924) by American writer Herman Melville (1819-1891). The original Billy Budd was depicted as extremely good-looking and charismatic, but exceptionally naive and rather dim-witted.

The two punk bands GBH and Conflict weren't around in 1977.
