The choir raised money, initially, to record a CD single for promotion and individual sales, through busking in city streets. They also held a fund-raising concert at the Melbourne Town Hall on 7 March 2007. For that performance they were supported by Melbourne Gay and Lesbian Chorus and by the Sydney Street Choir. Weekly broadcasts of the TV series commenced in early May 2007. The Choir of Hard Knocks later performed at the Sydney Opera House, which was broadcast in a second series as "Choir of Hard Knocks Opera House Special" in November.
