Note: I know that there are already some LOTR Christmas carols out there, and this is not indented to copy them. I also do not own Lord of the Rings.
Flying through the air, on a fell-beast in the sky, o'er the clouds we go, screeching all the way. Teeth on fell-beast shine, morgul blades are covered in grime, oh what fun it is to stab and screech at a hobbit on the ground, oh,
Stab and screech, stab and screech, stab stab screechy screech,
There's no way that wound will heal in the next millennium
Stab and screech, stab and screech, stab stab screechy screech,
There's no way that wound will heal in the next mil-en-e-um!
