the episode "Funny Ol' Business – Cops & Robbers". The sequence consisted of two police officers, one male and one female, walking down a street while images of Sun Hill were interspersed between them. This sequence was used for the first series only. It featured the first version of the iconic theme tune, "Overkill", composed by Charlie Morgan and Andy Pask. The theme is notable for its use of septuple meter. The end titles of the series simply showed the feet of the two police constables pounding the beat. In the show's second series, the opening sequence consisted of a police car, a Rover SD1, racing down a street with its siren wailing and its blue light flashing.

Mark Russell revamped "Overkill", giving it a jazz feel, with the majority of the theme played by a saxophone. The end credits of the series were also completely revamped. This time, the credits featured various images of the Metropolitan Police uniform, combined with
