Steptoe and Son - father and son run a junkyard. In this episode Harold (the son) discovers that (his father) Albert has 'neglected' to inform the tax department that his wife has died - over 30 years ago.
Father and son didn't always get on well in the script. Real life actors Wilfred Brambell and Harry H Corbett are said to have never got on well on set. Harry H Corbett was a fine straight actor who became typecast as Harold Steptoe and died young. Wilfred Brambell was an alchoholic convicted of cottaging and persistent importuning. In fairness it may have been the strain of his private life drove him to drink.
