What's in a Christmas Carol?

In 2005 Songs of Praise listed the following as the nations favourite Christmas carols:

Once in Royal David's City
Mrs Cecil Frances Alexander was a country schoolmistress. She wrote the carol to help her pupils understand the mystery of the birth of Jesus and her intenion was that it would not just be a Christmas Song but be used throughtout the year. It was put together with Henry Gauntlett's simple tune Irby and has become exactly what she didn't want a Christmas Carol.

O Come All ye Faithful
The original version was written in Latin and is commonly attributed to John Francis Wade, and is thought to have been written around about 1743. It was translated into the more familiar English version a century later by Frederick Oakeley and William Thomas Brooke.

Was written by Canon Michael Perry whilst he was a student at Oak Hill Theological College.

See Amid the Winter's Snow
This carol is one of my favourites though I don't think itwoudl have been amid snow that Jesus was born, it was written by Edward Caswall in 1858. The music Humility was written by John Goss in 1871.
