Well, almost over … I was driving back to Holyhead the next day when the mobile phone rang. It was a message from the Globe asking me to ring the Richard and Judy show. They were interested in doing a piece on OP. Was I in London? Well no, actually, Hilary told the researcher. We are on the M6 heading north-west. Could we be in London tomorrow? Not possible … meetings at home already planned. What about Wednesday?

Richard and Judy is a UK television chat-show that has made something of a mark for itself in recent times – an hour-long programme airing daily at 5 o'clock in the afternoon. It is produced in London by CactusTV for Channel 4, and in 2004 was attracting an audience approaching 3 million. It has a reputation for dealing with serious topics in an intelligent way. If I wanted the OP project to come to the attention of a large number of people, this was a proposal I could hardly ignore! And I was impressed that a popular programme like this should have shown an interest.

That is why I found myself on a train from Holyhead to London on the Wednesday morning. Not the best day to be in London, as it happened. There was a 24-hour tube strike.
