Advent calendar sessions again

The idea behind the bump's advent calendar was to tell it part of the Christmas story as we opened the windows but (a) not all the pictures are helpful - where did the lantern or sheepdog come into it? and (b) the parents-to-be are not that good at remembering details or even the words to Christmas carols that the pictures suggest to us. So, finally, I have tracked down some CDs of Christmas music/carols to play in lieu of mother only remembering the odd line here and there. Hope they are worth it.
