Now Clancy was a peaceful man
If you know what I mean
The cops picked up the pieces
After Clancy left the scene
He never looked for trouble
That's a fact you can assume
But nevertheless when trouble would press
Clancy lowered the boom!

Oh, that Clancy, Oh that Clancy
Whenever they got his Irish up
Clancy lowered the boom!
Boom, boom, boom, boom, boom, boom, boom

O'Leary was a fighting man
They all knew he was tough
He strutted 'round the neighborhood
A-shootin' off his guff
He picked a fight with Clancy
Then and there he sealed his doom
Before you could shout "O'Leary, look out!"
Clancy lowered the boom!

Oh, that Clancy, Oh that Clancy
Whenever they got his Irish up
Clancy lowered the boom!
Boom, boom, boom, boom, boom, boom, boom

Now Clancy left the barber shop
With tonic on his hair
He went into the pool room
And met O'Reilly there
O'Reilly said "For goodness sake
Now do I smell perfume"
Before you could stack
Your cue on the rack
Clancy lowered the boom

Oh, that Clancy, Oh that Clancy
Whenever they got his Irish up
Clancy lowered the boom!
Boom, boom, boom, boom, boom, boom, boom

Mulroney walked into the bar and ordered up a round
He left his drink to telephone and Clancy drank it down
Mulroney said "Who drunk me drink? I'll lay 'im in 'is tomb!"
Before you could tap the top of your hat, Clancy lowered the boom

Oh, that Clancy, Oh that Clancy
Whenever they got his Irish up
Clancy lowered the boom!
Boom, boom, boom, boom, boom, boom, boom

The neighbors all turned out for Kate O'Grady's wedding night
O'Riley said 'let's have some fun, I think I'll start a fight"
He wrecked the hall and kissed the bride, then pulverized the groom
In quick as a wink, before you could think Clancy lowered the boom

Oh, that Clancy, Oh that Clancy
Whenever they got his Irish up
Clancy lowered the boom!
Boom, boom, boom, boom, boom, boom, boom

O'Houlihan delivered ice
To Misses Clancy's flat,
He'd always linger for a while,
To talk of this and that,
One day he kissed her,
Just as Clancy walked into the room,
Before you could say the time of day,
Clancy lowered the boom!

Oh, that Clancy, Oh that Clancy
Whenever they got his Irish up
Clancy lowered the boom!

Sure it was the most beautiful sight you ever did see
When Clancy lowered the boom
