One of my stories which I published in an unfinished form was Christine's Magical Christmas, about two teenagers who, with their high school choir, get pulled into a performance of J. S. Bach's Weihnachtsoratorium, or the Christmas Oratorio.
The Story is about how some six high school choirs are invited to learn and perform the Oratorio, after which four from each school go on to sing it at a concert, with professional soloists and a Baroque orchestra. In the story, I describe how a certain solo aria is sung with a very difficult solo violin accompaniment. But I just saw a video of that very song this morning, and---guess what! It is accompanied by two solo violins! So now the story has to be 'repaired'.
More than repaired, the story has to be completed; this is not a story that can be left the way it is; it sits there, glaring at me, demanding a completion. Well, I must make it believe that I fully intend to complete it sometime this Christmas.
