On the break, a bunch of us huddled with our hands over the radiators, whose heat seemed to be going out the glass windows instead of into the church. Snacks included cheese, and I ate several bites, on the theory that they would serve the same purpose as eating blubber to warm up in the cold. It might even have worked a little.
The singing, however, was glorious. A small group, in a small church, filling it up with rich sounds. We worked on a couple of the big fugues, tossing the lines back and forth, flowing like water.
