The version I heard, from my father, who heard if from his grandfather in Donegal, Ireland goes like this:

THE WEDDING OF LARRY MCGRATH

Chorus
Dammit, it was a terrible tear
Me and herself and her mother were there
I may get mixed up in the wheels of a train
If ever I go to a wedding again

The first one to sing was a Mickey O'Hara
Who gave us a verse of the tar-a-rar-rara
Poor Mickey's remains were wheeled home in a barra (wheelbarrow)
The night of the wedding of Larry McGrath

Chorus

The next one to sing was an ould Jenny Russel
And she couln't sing so she started to whustle (whistle)
Then somebody hit her a kick in the bustle
The night of the wedding of Larry McGrath

Chorus

All of a sudden big Seamus McGinty
With several bakers he kicked up a shindy
He lifted the poker and killed about twenty
The night of the wedding of Larry McGrath

Chorus

I never heard any other verses, but that doesn't mean that my great-grandfather never sang them. I might swipe a few from the postings here.
