I think they are all pretty dull to be honest - Once in royal David's city a carol of celebration of a most important birth?? It plods along like something for a funeral cortège! Same for Oh Little Town of Bethlehem and Away in a Manger - who died??!!
Rousing songs of celebration are few and far between but in the Scunner Itunes Christmas Megamix, Hark the Herald Angels Sing gets in
The holly and the ivy,
When they are both full grown
Of all the trees that are in the wood
The holly bears the crownSo why mention the ivy at all then!!! Merry Christmas!
