We turned up the next day and realised we hadn’t checked out the tour times. We were in time to have a little wander and return in forty minutes. There was now a large crowd gathered around a man with an umbrella held aloft and it seemed an unmanageable group. But we were divided into three groups as there were three volunteers and we were allocated to Joy. She led us to the cathedral to begin our tour and at first our stops were to places we had just been, but of course knew nothng about. Later we covered places we had not seen at all. She managed a multinational group in a calm relaxed manner and we learned about disease, toilets, architecture, Jane Austen, vaccination, Georgian nightclubs and fashion in an easy, light hearted style and two hours passed quickly.
