Well, it's new to me, anyway. I usually love the traditional Christmas carols. But this song - I think it's from late 70's/early 80's - really gets to the point. I love the lyrics which tell the Christmas story, and I love the joy that the Caribbean style of music gives to it.
The name is "Mary's Boy Child/ Oh, My Lord" by the group Boney M.
I hope you enjoy it as much as I do. Merry Christmas, everyone!
