I didn't know that about Little Drummer Boy. To be honest, I wish I didn't know it now.
I love carols. One of my favourites is the Cherry Tree Carol, a traditional English carol which shows that our ancestors had considered how cross Joseph must have felt about Mary's pregnancy. Joan Baez and Judy Collins have both recorded lovely versions.
I am not a big fan of Mistletoe And Wine or Frosty the irritating Snowman. I like most of the songs already mentioned but I think my favourite Christmas songs are Gaudete by Steeleye Span and Elvis's wonderfully snarly Santa Claus Is Back In Town.
The first year that my DD and her family moved to the USA, they said that Christmas there didn't feel the same. One of the differences was that the songs that we hear every Christmas, playing everywhere, aren't usually played there. Then one day, when they were in a mall, I Wish It Could Be Christmas Every Day started to play. At the sound of Roy Wood's voice, DD and teenage DGD burst into homesick tears.
