When I rang Lisa on the way back from the pancakes at 9:45pm ish, she told me they'd had a power cut all evening. Liam was delighted - "like camping using torches, only with all your stuff!"
I thought of the power-cuts of the early 70s, the three day week etc, due to miners strikes...
I got there just before 11pm. Fortunately, it was only a small area affected - the light pollution off the low clouds meant there was no problem walking around. The lights came back at about 11:05.
