XD This is simply hilarious. It's done in the true Gregorian style, and yet the lyrics (which I can decipher perfectly well, thank you) are the ones we all know and love, if slightly abridged. For instance, the opening lines go like this: 'Rudolph was a deer. He had a red nose. If you ever saw it, you would say it glows.'
Whoever did this, I love them.
In Pace Christi,
