Choristers from King's College Choir preparing for this years BBC recording of Carols from King's which is broadcast on Christmas Eve.
Choristers in Cambridge have been doing their final rehearsal for one of the world's most famous carol services.
The 16 boys have spent weeks practising at King's College Chapel for the hugely popular Carols from King's, which has been televised by the BBC for more than 60 years.
Every year millions of people across the globe watch the traditional service, which was first broadcast in 1954 and will be shown this year on BBC2 on Christmas Eve.
The special service is a shortened version of the college's renowned live Christmas Eve service a Festival of Nine Lessons and Carols and instead has just seven readings.
It always begins with a lone choirboy singing Once in Royal David's City and features a mix of traditional readings and hymns.
This year's highlights include a 15th century German carol, with the music arranged by Stephen Cleobury and The Shepherd's Carol, with music by Bob Chilcolt.
