I had a hat when I came in, I hung it on the rack
I'll have a hat when I go out
Or I'll break somebody's back

Casey wore his brand new hat to Murphy's wake last night
Someone stole my hat boys
It started up a fight
Casey smashed the furniture, the radio as well
I nearly woke the corpse up
When he began to yell

I had a hat when I came in, I hung it on the rack
I'll have a hat when I go out
Or I'll break somebody's back
I'm a peaceful, loving man, I am
and I don't want to shout
But I had a hat when I came in
I'll have a hat when I go out

Casey kept on shouting, boys, they couldn't keep him quiet
Someone phoned the cops up to come and stop the riot
Two cops rushed into the room, but Casey laid them out
I fired ‘em through the window
They both heard Casey shout

I had a hat when I came in, I hung it on the rack
I'll have a hat when I go out
Or I'll break somebody's back
I'm a peaceful, loving man, I am
and I don't want to shout
But I had a hat when I came in
I'll have a hat when I go out

I'm a peaceful loving man, I am
and I don't want to shout
but I had a hat when I came in
I'll have a hat when I go out

Casey kept on shouting, boys, till One-eyed Paddy Flynn
Socked me in the whiskers with a great big rolling pin
It knocked poor Casey senseless
It was an awful clout
As he lay there unconscious, Casey shouted out

I had a hat when I came in, I hung it on the rack
I'll have a hat when I go out
Or I'll break somebody's back
I'm a peaceful, loving man, I am
and I don't want to shout
But I had a hat when I came in
I'll have a hat when I go out

I'm a peaceful, loving man, I am
(I had a hat when I came in
I hung it on the rack I'll have a hat when I go out
I had a hat when I came in
I hung it on the rack I'll have a hat when I go out
Or I'll break somebody's back)
