Other features of the series were Arthur's constant and ambitious use of obscure Cockney rhyming slang, the derelict sites used as locations, and the episode titles, which contained references to well-known phrases and names (e.g. "Guess Who's Coming to Pinner"). Another strong character was Arthur's failed nemesis, the hapless policeman Detective Sergeant "Charlie" Chisholm (Patrick Malahide), who was always close to detecting Arthur's crimes but was not quite clever enough to catch him.
The original theme tune, I Could Be So Good For You, was written in 1979 by Patricia Waterman and Gerard Kenny, and sung by Waterman.
Waterman left the show towards the end, and his character was replaced in 1989 by Ray Daley, Arthur's nephew, played by Gary Webster. The theme tune was replaced by an instrumental version of Waterman's song, credited to "Kenny".
A minder is also someone who is assigned to watch over another person, usually to observe their actions and keep them in line. This typically happens to visitors in totalitarian countries, or in political campaigns.
