I have one to get - 41D (from the Oxford Book of Carols) "In lands long in shadow, his churches ?????" (5) - I have A?I?E - can it be ARISE or ABIDE?
The letters I have for the three-word phrase anagram linked to Christmas are: E R U D I T O M E T B L L Y M plus the second letter of the above answer.
My best wishes for Christmas and the New Year to all fellow ABers. May the coming year be better than this one!
