A couple of points: a) The Digital Tradition is certainly NOT an iron-clad reference for "correct" words. We're as good as our contributors and editor(s). And no better. If you find (or think) we're in error somewhere, please let me know.

b) The study of Mondegreens is a fascinating one. COnsider the Christmas trinity of "Round John Virgin, mother and child", or the two animal-based hymns, "Gladly, the Cross-Eyed Bear" and "Lead On, Thou Kinky Turtle".
