The choir performance went off well. There were a lot of graduate students and staff there, all very youngish looking. The performance sounded good and strong and some people were quite moved, they said. One women who had had a stroke sang a solo verse of Silent Night. There was nice food there which I took advantage of, then trotted off home again on the bus. Of course I was very tired in the evening and had to fight the temptation to go to bed after tea.
