Thanks for the link, Gavin. You did a good job of fitting the lyrics and tune together. It sounds right.

I just went to the DT to see what this tune is, and found myself thinking "I've heard this before."

Yes, it has been used for the Christmas song

"Bles-sed be that maid, Ma-rie-ee;
bo-orn He was of he-r bo-o-dy."
