The idea for 'Z Cars', reputedly, came when writer Troy Kennedy Martin was ill with the mumps, and was listening to police radio messages to wile away the time.
With a very strong cast, including Stratford Johns and Frank Windsor, 'Z Cars' was based in the Liverpool area and ran from 1962 to 1978. It showed policemen as far from perfect, and was groundbreaking in its day.
The 'Z Cars' theme is still played at Everton FC home matches, to greet the home team when it runs onto the pitch at Goodison Park.
