That's Right!
I missed that one!
Neither was Adeste Fideles.
I Do think they had to pick between We Three Kings & Mary's Boy Child, and they
went forward with We Three Kings--- as for Adeste Fidele's this would of been Chloe's
2nd Act solo after Santa Claus Is Coming to Down, but since Chloe's absense and
Susan's participation instead, I don't think it would of suit Susan compared to Midnight Clear.
