Thanks to a comment yesterday, here’s Did You Know? from EMU Music.
We did use it for a couple of Christmases when it came out, and then it slipped from mind.
Good thing that the lyrics were composed by Simone Richardson, so it escapes an annual accusation of man-splaining. (cough Mary, Did You Know? cough)
Also, the lyrical cleverness of the composition moves from Mary to the shepherds to an allusion of Simeon and Anna demonstrates that each praised God for what they did know (incomplete as that may have been) and invites those of us who know so much more to join their song.
