Trivia: The story behind why Trigger calls Rodney Dave is that apparently Roger Lloyd Pack kept getting names mixed up during rehearsals early on in the show's history. "Dave" came from David Jason when he was actually with Nicholas Lyndhurst [Rodney]. It stuck and quickly became part of the show's immense appeal.
Trivia: In the closing song, one of the lines is "God Bless Hooky Street". Hooky is British slang for something stolen or which has been acquired illegally.
Trivia: David Jason was the fourth choice actor to play the character Del. Jim Broadbent (who later went on to play Roy Slater), Enn Rietel and Billy Murray were all asked before Jason but all turned it down due to other commitments. Jason was actually only picked four days before filming started on the first episode.
Trivia: John Sullivan had intended for pop duo Chas & Dave to sing the theme song, but they were unavailable. Sullivan was persuaded by producer Ray Butt to sing the song himself.
Trivia: The show was originally filmed on location in Peckham, but as the show grew in popularity, filming was increasingly interrupted by tourists. And so, the location of filming was changed, but the setting remained the same.
