The flute had been standing in a corner near a window (well out of the way of the basses' big feet!) and I can only think that it'd just got too cold. Perhaps I should have stuffed it down my tights! (Any ideas?!) The next two pieces went fine and I played along with a bunch of carols no problem. (The one good thing was that having been battling with laryngitis all week and croaking my way through the first half, after playing my singing voice magically came back.)
A learning experience!
