throwing in the towel

At this point, I can foresee that we will not complete the entire project. There are a few more weeks of the school year, with a full choir, and then five weeks of summer services with soloists providing music.
The number of singers decreases as the summer draws closer... and we are still dealing with the loss of strongest tenor. One of our strongest basses will be graduating and leaving for college soon. The choir has responded very well to this long project, but I think they are tired and might not appreciate one final push. These final Sundays of the school year are also jammed full of special events- church school Sunday, teacher recognition, graduation, confirmation, etc.
