This is pretty good. I sang this in High school for a state contest. There is a third verse, actually it is the second verse:

My lodging is a cellar here
Upon a cask I am seated
The choicest wines my heart can dear
To me is freely meted(sp?)
The cellar man deserves my praise
From duty never shrinking
He deftly fills the glass i raise
When drinking, drinking, drinking.

I'm haunted by a demon grim
the fiend of thirst they call him
and fill my tankard to the brim
when err I would appall him.
the world to one vast brotherhood
one chain of roses linking
I never feel my heart so good
as when drinking, drinking, drinking.

To banish thirst i vainly haste
it comes back all the quicker
such is the lot of all who taste
the Rhines inspiring liquor
i cannot see what harm is done
if to the floor I'm sinking
i never injure anyone
when drinking, drinking, drinking!

I corrected some of the words.
Enjoy!
