Irish Drinking Song Lyrics

Advisory - the following lyrics contain explicit language:
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 roundand 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
i'll admit it sounded weak
for mary McGregor finally got some sleepwell 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
