The major TV broadcasting event of the year is the BBC's Carol's from King's sung by the choir of King's College Cambridge on Christmas Eve, usually on BBC2 around 6.00 pm. Other Christmas broadcasts include Midnight Mass and Christmas Morning Eucharist and both the BBC TV and ITV broadcast one or more of these services.
On a more regular basis, the worship from BBC's Songs of Praise is frequently lead by a Cathedral Choir and both the BBC and ITV broadcast major State and Royal services from Westminster Abbey and St Paul's Cathedral. BBC TV broadcasts can be viewed again via their website .
'Carols from King's' - The Choir of King's College, Cambridge
This service is not, as many imagine, a TV broadcast of the Festival of Nine Lessons and Carols, but a pre-recorded service, especially for television, filmed some two weeks before Christmas. This service contain both lessons and Christmas readings with variations in the music from that of the 'Nine Lessons' service.
A full rehearsal takes place on a Saturday and the television recording is made on the Sunday, with a congregation present.
