The Odd Man was the first of a trilogy of police series produced in the 1960s by Granada TV, linked by the presence of pompous but increasingly genial police Chief Inspector Charles Rose. It originally dealt with the investigations of theatrical-agent-cum-detective Steve Gardiner, and his encounters with the police in the form of Chief Inspector Gordon and DS Swift. By the second season, Gordon had been replaced by Rose.
The characters of Rose and Swift were then given their own series, It's Dark Outside, which ran for two seasons, with Barron being replaced in the second series by Anthony Ainley as DS Hunter.
The third and final series in the trilogy, Mr Rose, saw Rose in retirement in Eastbourne, attempting to write his memoirs, but instead being drawn into private detection. The theme tune for this series was by John Snow, and issued on a single as a cover version by Roy Budd and the Tony Hatch Orchestra on the Pye Records label in 1967. A separate cover version was recorded on the album "Time For TV" by Brian Fahey and his Orchestra, on the Studio 2 Stereo label. John Snow's original recording was recorded by the De Wolfe mood music library, and is not commercially available.
