For many it’s the true start of Christmas- and it takes place right here in Cambridge.
The Festival of Nine Lessons and Carols has just finished at King’s College Chapel, with people all over the world pausing to listen to the pitch-perfect harmonies of the college choir.
The annual service began at 3pm, but preparations for the big day have been going on for months, as the choir builds up to its biggest day of the year.
It started, as ever, with one lucky choirboy selected to sing the opening solo to Once the Royal David’s City, the carol that always heralds the beginning of the service.
As well as much-loved Christmas classics, including Ding Dong Merrily On High, While Shepherds Watched Their Flocks By Night and O Come All Ye Faithful, it featured a brand new carol, composed specially for the occaision.
This Endernight , was written by composer and broadcaster Michael Berkeley, eldest son of Sir Lennox Berkeley and a godson of Benjamin Britten.
A copy of the choir’s rendition of the piece, which was based on an anonymous c1400 text, is available to download from iTunes here .
Millions of people tuned in to listen to the service all over the world, but it can be heard again in its entirety on the Radio 4 website.
