Two very brief excerpts from Radio 4 last week. First, my wife turned on her radio in time to hear an actor in the afternoon play utter the words: ‘But Bob, you’ve been helping young disadvantaged black kids all your life!’ At which point, she turned off. Two days later I switched on my car radio and the display announced a ‘radical updating of Oliver Twist’ and I had just enough time to hear an actor say something like: ‘Quick, come quick! Babatunde has been shot in de leg by de gangs!’ before I too turned off.
