Does anyone know the parody written about a local Dublin character who drank the pint of the stranger who came into the bar in Glasnevin, Dublin.

It follows the original fairly closely but changes phrases here and there.

I heard it twice about 30 years ago and the man who said it from memory is long since dead. Just a long shot.
I remember snatches and some of it goes like this; the verse about the eerie music becomes something like:

In a buckskin shirt that was dazed with dirt he sat, and I saw him sway,
Then he clutched the keys with his talon hands-- oh God! but that man can't play.
Were you ever out on the Finglas road and your mind half crazed with beer
And the graveyard wall it seemed to call "you should be lying here"

and the end becomes

I'm not so wise as those lawyer guys, but strictly between us two
The woman that kissed him and -- drank his beer -- was the lady who's known as Lou.
