The holly and the ivy

A Facebook friend, currently bearing her fourth child, confessed a special affection for this sort of song in this season this year:
"The holly bears a prickle as sharp as any thorn, / And Mary bore sweet Jesus Christ on Christmas Day in the morn."
Soprano singing above verse looks amazingly like me when I first sang this song. Including the red cassock and simple white ruff. YouTube - The Holly And The Ivy Link
