1. I'm Terence O'Reilly. I'm a man of renown.
I'm a thoroughbred to the backbone.
I'm related to O'Connor. my mother was queen
Of China, ten miles from Athlone.
But if they'd let me be, I'd have Ireland free;
On the railroads you would pay no fare.
I'd have the United States under my thumb,
And I'd sleep in the President's chair.

CHORUS: Are you the O'Reilly that keeps this hotel?
Are you the O'Reilly they speak of so well?
Are you the O'Reilly, they speak of so highly?
Gor blime me, O'Reilly, you are looking well.

2. There's Shamus O'Reilly who kept the hotel.
He's assigned to the Commissary.
Back home in Old Dublin he did very well,
But he's now working for the army.
He once served at the "Pub," but he's now serving grub,
And it's flavored with powder and lead.
He took the King's shilling to go do his killing,
But he's cooking for sojers instead.

3. Young Ludwig O'Reilly—that may be his name—
In the trench on the enemy's side—
I glimpsed his big helmet and potted the same,
And to "helmit" went Ludwig's right eye.
Then his brother named Fritz nearly gave us all fits.
We were laughing at what he had done,
When up rose the blighter, a bally good fighter,
And he started us all on the run.
