The 1960s brought new freedoms in society, which television tried to reflect. Among the guests on this edition are Joan Hooley, discussing television's first interracial kiss, and Peter Wyngarde, expressing regret at working in blackface.

A look back at how Britain used to entertain itself in the days of austerity and the three day week, with personal safety not considered. Contributors include Tony Blackburn, talking about his own experience singing to five live lions.
