Keith Clapham was with Exeter City between 1972 and 1977 during which time he played most of his football during his first three seasons with the club. He joined City from Bournemouth and later, after playing in Australia, returned to live in Dorset. 

He started as an apprentice with Bournemouth although, after signing a full contract in September 1970, didn't make a first-team breakthrough and was released at the end of the 1971/72 season.

Signing for Exeter City Keith made his debut at Torquay United on 23 September 1972 and appeared in 26 games during his first season followed by 34  and 21 in the next two campaigns. He then made a solitary appearance in 1975/76 and nine during his fifth and final term with the club. After being transfer-listed in October 1976, he left to play in Australia in March 1977.

Keith settled in the Bournemouth area and returned to St James' Park and visited the club museum in March 2023.
