Jonathan James English was an English-born Australian singer, songwriter, musician and actor. He emigrated from England to Australia with his parents in 1961. He was an early vocalist and rhythm guitarist for Sebastian Hardie but left to take on the role of Judas Iscariot in the Australian version of the stage musical Jesus Christ Superstar from May 1972, which was broadcast on television. English was also a solo singer; his Australian top twenty hit singles include "Turn the Page", "Hollywood Seven", "Words are Not Enough", "Six Ribbons" and "Hot Town".

Jesus Christ Superstar is a sung-through rock opera with music by Andrew Lloyd Webber and lyrics by Tim Rice. Loosely based on the Gospels' accounts of the Passion, the work interprets the psychology of Jesus and other characters, with much of the plot centered on Judas, who is dissatisfied with the direction in which Jesus is steering his disciples. Contemporary attitudes, sensibilities and slang pervade the rock opera's lyrics, and ironic allusions to modern life are scattered throughout the depiction of political events. Stage and film productions accordingly contain many intentional anachronisms.
