The leader of my church choir has been soliciting music suggestions for the Advent & Christmas seasons. One of our members, after protesting that it's still August, still summer - too soon! went on to suggest a parish Christmas carol party. Any interested parties could just show up in the church social hall, free to bring instruments, voices and perhaps snacks, and we could sing ourselves hoarse. I think that sounds like a WONDERFUL idea! I sure hope it happens.
I don't know if the Chief would come - he's not much for singing. However, if I can assure him that some of the parishioners will be bringing their babies and toddlers, I'm sure I'd have NO trouble persuading him to attend with me.
