It was created by 15-year-old schoolboy Vivian Berger by pasting the head of Rupert onto the lead character of an X-rated satirical cartoon by Robert Crumb. Oz was one of several 'underground' publications targeted by the Obscene Publications Squad, and their offices had already been raided on several occasions, but the conjunction of schoolchildren and what some viewed as obscene material set the scene for the Oz obscenity trial of 1971. In one key respect it was a virtual re-run of the second Australian trial – the judicial instruction was clearly aimed at securing a conviction, and like Gerald Locke in Sydney, the judge hearing the London case, Judge Michael Argyle, exhibited clear signs of bias against the defendants.

Lennon explained how the song title changed
