It's documented, pretty much word for word, back into the 1770s, and according to some sources, is set to a tune that dates back into the 1600s.
Of all the money that e'er I had,
I spent it in good company.
And all the harm I've ever done
Alas! It was too none but me.
And all I've done for want of wit
To mem'ry now I can't recall
So fill to me the parting glass
Good night and joy be with you all
Of all the comrades that e'er I had,
They're sorry for my going away.
And all the sweethearts that e'er I had
They'd wish me one more day to stay
But since it falls into my lot
That I should rise and you should not
I gently rise and softly call
Good night and joy be with you all.
If I had money enough to spend
And leisure time to sit a while
There is a fair maid in this town
That surely has my heart beguiled
Her rosy cheeks and ruby lips
I own she has my heart in thrall
Then fill to me the parting glass
Good night and joy be with you all.
