Torok, i've tried my best:
Long have we herded the vale of light
In dark times when the frost visited us
We told stories from the past, of norse heroics.
between the spruce branches, the Yule goat and the fire
The sun will burn again and the lord will hunt again
The siblings make a sacrifice to Freyr
Then the horns will sound, raw and overblown,
and we will dance naked and drunk around the fire
Everything beautiful, comes to an end
We drank all the liquor, can't get it up anymore
Twelve nights of mating, twelve days of beer
My legs are like lead, my eyelids are heavy
The mixture of wheat, piss and seed
Just one more swallow, another for the deed
Another for the gods, another one for you
For the dawn brings us the new beginning
Yule Goat == Joel Goat == The Christmas Goat like you referenced.
Freyr is indeed the Norse god of fertility
Google Translate does really crappy job on this song.
