Irish Drinking Song lyrics

I stumbled in at 2am all drunk
And full of smoke
My wife said "I've had enough"
That's it, I'm sick, get out!"
So I stumbled down to kelly's pub
Across the edge of town
And I told the boys me story
And we had another round
[ Lyrics from: http://www.lyricsmode.com/lyrics/b/buck_o_nine/irish_drinking_song.html ]
And we'll drink and drink and drink
And drink and drink and drink and
Fight-yeah! [2x]
And if I see a pretty girl
I'll sleep with her tonight
I'll drink and drink and drink and
Drink and drink and drink and fight...

And mary McGregor
Well she was a pretty whore
She'd always greet you with a smile
And never lock her door
But on the day she died
All the men in town did weep
For mary McGregor finally got some sleep

Well I once loved a girl
A child I'm told
I gave her my heart
And she gave me a cold
So now I sit standing
Out in the pouring rain
I'll stumble back to kelly's pub
And cry away me pain
