We seem to have lost our British sense of humour. It's a great shame. We have to be so careful nowadays; we have lost a lot of humour because people are too frightened of getting too near touchy subjects.
The Christmas of 1965 was a Yuletide with a difference at my parents' tiny terrace house in North London: it was the first time my family had been able to see me on television.
