Simon Russell Beale takes a journey through Italy, Britain, Germany and Austria as he explores how the sound of Christmas has evolved in response to changing ideas about the Nativity. His story takes us through two millennia of music, from a fragment of papyrus preserving the earliest known piece of Christian music to the stories behind Hark! The herald angels sing, Silent Night and In the bleak midwinter, and the work of popular Christmas composer, John Rutter all performed by Harry Christophers and The Sixteen. "A Choral Christmas"; Simon Russell Beale introduces a programme of choral music for Christmas from across the centuries, featuring performances of some of the works featured in the accompanying documentary. Harry Christophers and The Sixteen, perform music including J.S. Bach's harmonisation of the medieval carol In dulci jubilo, A spotless rose by Herbert Howells and the Christmas text O magnum mysterium, set as a motet by Tomás Luis de Victoria.
