Were up MacCahir Og your face
You're brooding o'er you're old disgrace
That black FitzWilliam stormed your place
He sent you to the Fern
Grey said victory was sure
Soon the firebrand he'd secure;
Until he met at Glenmalure
With Fiach MacHugh O'Byrne

Curse and swear Lord Kildare
Fiach will do what Fiach will dare
Now FitzWilliam, have a care
Fallen is your star, low
Up with halberd out with sword
On we'll go for by the lord
Fiach MacHugh has given the word
Follow me up to Carlow

From Tassagart to Clonmore
There flows a stream of Saxon gore
Oh, great is Rory Oge O'More
At sending loons to Hades
White is sick and Grey is fled
And now for black FitzWilliam's head
We'll send it over, dripping red
To Liza and her ladies

Curse and swear Lord Kildare
Fiach will do what Fiach will dare
Now FitzWilliam, have a care
Fallen is your star, low
Up with halberd out with sword
On we'll go for by the lord
Fiach MacHugh has given the word
Follow me up to Carlow

Curse and swear Lord Kildare
Fiach will do what Fiach will dare
Now FitzWilliam, have a care
Fallen is your star, low
Up with halberd out with sword
On we'll go for by the lord
Fiach MacHugh has given the word
Follow me up to Carlow

See the swords of Glen Imayle
They flash all o'er the English pale
See all the children of the Gael
Beneath O'Byrne's banners
Rooster of the fighting stock
Would you let a Saxon cock
Crow out upon an Irish rock?
Fly up and we'll teach him manners
Curse and swear Lord Kildare
Fiach will do what Fiach will dare
Now FitzWilliam, have a care
Fallen is your star, low
Up with halberd out with sword
On we'll go for by the lord
Fiach MacHugh has given the word
Follow me up to Carlow

Curse and swear Lord Kildare
Fiach will do what Fiach will dare
Now FitzWilliam, have a care
Fallen is your star, low
Up with halberd out with sword
On we'll go for by the lord
Fiach MacHugh has given the word
Follow me up to Carlow
