This is the famous carol service that we spoke about; it will be available (live) via the iPlayer at 3pm this afternoon (Monday Christmas Eve, Radio 4):

(although I doubt that the laptop's speakers will do it justice)
A Festival of Nine Lessons and Carols, live from the candlelit chapel of King's College, Cambridge, marks the beginning of Christmas. It is based around nine Bible readings which tell the story of the loving purposes of God. They are interspersed with carols old and new, sung by the world famous chapel choir who also lead the congregation...
It is also on BBC2 at 6:15pm, but that is pre-recorded & not live.
