Join Simon Callow as he uncovers the origins of Silent Night, from the Austrian village of Oberndorf to the city of Salzburg, birthplace of the worlds favorite carol. Two impoverished children, Joseph Mohr and Franz Gruber, met one day in a country church, where they united Grubers music and Mohrs text into this classic carol about the birth of a third poor boy on a quiet night in ancient Palestine.
