Fortunately, the pain wasn't severe enough to keep me from doing the square dance in Stomp Your Foot. It went reasonably well, considering we only learned the routine a week or so ago. In general, the concert went pretty well. I only remember one semi-train wreck in Hark I Hear the Harps Eternal, at a spot where some people aren't sure quite when to come in. At least it was an improvement over the last time we did it.
I hope that I don't injure myself during my trip, especially on the way to/from France. I don't like to travel while injured, especially on airplanes.
