John who lives in a Cambridgeshire village (5)
I believe the answer is:
elton
I believe this is a double definition.
'john' is the first definition.
(musician Elton John)
'a cambridgeshire village' is the second definition.
(village in Cambridgeshire)
'who lives in' is the link.
(Other definitions for elton that I've seen before include "..... Jonn (musician)" , "Sir - - John, singer songwriter" , "First name of singer/songwriter born Reginald Dwight in 1947" , "One John" , "Let on he's John, the singer" .)
