These are lyrics from another song about the famous saint.

THE GLENDALOUGH SAINT

In Glendalough lived an old saint,
Renowned for his learning and piety.
His manners were curious and quaint,
And he looked upon girls with disparity.

CHORUS:

Ri fol di dol, fol di dol day,
Ri fol di dol, fol di dol laddy,
Ri fol di dol, fol di dol day,
Ri fol di dol, fol di dol laddy.

But as he was fishin' one day,
A catchin' some kind of trout, sir
Young Kathleen was walkin' that way
Just to see what the saint was about, sir.

You're a mighty fine fisher', Says Kate,
"tis yourself is the boy That can hook them,
But when you have caught them so nate,
Don't you want some young Woman to cook them?'

Be gone out of that', said the saint,
'For I am a man of great piety,
Me character I wouldn't taint,
By keeping such class of society.

But Kathleen wasn't goin' to give in,
For when he got home to his rockery,
He found her sitting therein,
A-polishing up of his crockery.

He gave the poor creature a shake,
Oh, I wish that the peelers had caught him:
He threw her right into the lake,
And of course she sank Down to the bottom.

It is rumoured from that very day,
Kathleen's ghost can be seen on the river
and the saint never raised up his hand.
For he died of the right kind of fervour.
