An email from a researcher doing a documentary for BBC3 on the history of teenagers arrives. That’ll be short, I think. She wants to talk to me about ways of presenting the Sixties to today’s teenagers, who she has discovered know nothing about the period. BBC3, with a viewer age range of 16 to 24, doesn’t do history documentaries as a rule, so it’s a bit of an experiment. She phones. ‘We’ve got a bit of development money for the project and I saw you had a book out about the Sixties. The reviews said you were involved with young people, and I was wondering if you had any ideas for grabbing the attention of modern teenagers about what teenagers were like in the Sixties.’ A researcher. She had (mis)read a review or two of a book she hadn’t even looked at. Might be worth a phone call.
