Chris,

There is another verse to the song that most people do not sing. We used it as the second last verse.

And it came to pass we should go to mass
On the Immaculate Conception.
The foreman met us at the gate
And gave us a terrible reception:
"Get down them sewers, ye Kerry whores,
And never mind your prayers,
For the only God is a well filled hod
With McAlpine's Fusiliers."
