The sound of Z cars >>>> The sweet silver song of the lark
You probably know the Z Cars theme is based on the sea shanty, Johhny Todd, a song based on the sadness and disappointment of a man who goes to sea and comes back to find his fiance has married another (obviously a duplicitous redshite);
Johnny Todd came home from sailing,
Sailing o'er the ocean wide,
But he found that his fair and false one
Was another sailor's bride.
All you men who go a-sailing
For to fight the foreign foe:
Don't leave your love like Johnny,
Marry her before you go.
