The popular service to hold on Christmas Eve was made very famous by the choir from King's College, Cambridge, which was reckoned to be the best Church choir in the world at the time.
The Service was first performed at King's College in 1918 as a way of the college celebrating the end of the First World War. In 1919, the new college Dean, Eric Milner-White changed the opening hymn/carol to be ‘Once in Royal David’s City’ and set the main order and structure of the lessons/readings as it still is today.
Today, you can share in the live, world-wide Christmas Eve broadcast of a service of Biblical readings, carols, and related seasonal Classical music.
