A Christmas Without Snow - 1980 (DVD) - UK Seller

A divorced woman moves to a new city with her child, trying to build her life again. She joins the choir of a local church but has some personality conflicts with the choirmaster, a curmudgeonly old gentleman who will accept nothing but perfection from his group. As Christmas approaches and the choir practices for a big show and the director pushes them all to their emotional limits, she contemplates quitting the group.
