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. Other Christmas broadcasts include Midnight Mass and Christmas Morning Eucharist and both the BBC 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 .

A full rehearsal takes place on a Saturday and the television recording is made on the Sunday, with a congregation present. For in-depth and fascinating article on the preparations for and recording of Carols from King's.
