Gang from Cheshire town on the radio (4)
I believe the answer is:
crew
'gang' is the definition.
('crew' can be a synonym of 'gang')
'cheshire town on the radio' is the wordplay.
'cheshire town' becomes 'crewe' (I've seen this before).
'on the radio' indicates a 'sounds like' (homophone) clue.
'crewe' is a homophone of 'CREW'.
'from' acts as a link.
(Other definitions for crew that I've seen before include "Ship's company - bragged" , "Rowing team" , "Company working together" , "Train team" , "eight > was sounding shrilly" .)
