I don't know if they fit for Yuletide or not but you're welcome to use, change or scrap them - was just fun to play around a bit. :D
We three orcs of dol dinen are
bearing lives controlled by Angmar
Ne'er a fountain by this big mountain
and we must go to war
Arrgh war of power, war of greed
War that makes the masses bleed
We'll surround them and we'll bound them
Then we can finally feed
Born a slave to serve Angmar's will
We were made to control and kill
Elves and dwarvsies with our big wargsies
if we desire a meal
Arrgh war of power, war of greed
War that makes the masses bleed
We'll surround them and we'll bound them
Then we can finally feed
Hobbit-heads on spikes for a snack
That is why we like to attack
They taste yummy to my tummy
and they don't make me yack
Arrgh war of power, war of greed
War that makes the masses bleed
We'll surround them and we'll bound them
Then we can finally feed
Man's too tough but he still tastes fine
if we let them soak in a brine
cloves and cumin, I love some human
with more than a splash of white wine
Arrgh war of power, war of greed
War that makes the masses bleed
We'll surround them and we'll bound them
Then we can finally feed
See us now, our weapons will rise
We will make homemade Cricket Pies
All our filling is made from fresh killing
we'll surely beat the flies
Arrgh war of power, war of greed
War that makes the masses bleed
We'll surround them and we'll bound them
Then we can finally feed
