Here is the version I use, but it is only one version of the song and not set in stone.

Oh, me name is Pat Sweeney. I'm a cagey old man,
And a ramblin' young rover I've been.
So be easy and free when you're drinking with me.
I'm a man you don't meet every day.

I have acres of land and I've been of command,
I've always a shilling to spare.
So be----

I will take out my dog and my gun for to shoot,
and I'll ramble round rivers and lakes.
So be----

Come fill up your glass, be it whiskey or beer,
Whatever the price I will pay.
So be---

Repeat first verse and chorus and end.

Hope that helps you, just be aware that there are others versions too.
