ST. PATRICK WAS A GENTLEMAN
Saint Patrick was a gentleman; he came of decent people,
In Dublin town he built a church and on it put a steeple,
His father was a Callaghan; his mother was a Brady,
His Aunt was an O'Shaughnessy and his uncle was a Grady.
CHORUS: Then success to bold St. Patrick's fist, he was a saint so clever,
He gave the snakes an awful twist and banished them forever.
There's not a mile in Ireland's Isle where the dirty vermin musters,
Where'er he put his dear forefoot he murder'd them in clusters,
The toads went hop; the frogs went plop, slap dash into the water,
And the beasts committed suicide to same themselves from slaughter.
Nine hundred thousand vipers blue he charm'd with sweet discourses,
And dined on them at Killaloo in soups and second courses,
When blind worms crawling on the grass disgusted all the nation,
He gave a them a rise and open'd their eyes to a sense of their situation.
The Wicklow hills are very high, and so's the hill of Howth, sir,
But there's a hill much higher still, Ay higher than them both, sir,
"Twas on the top of this high hill St. Patrick preached the "sarmint,"
He drove the frogs into the bogs, and bothered all the varmint.
Let me know if you need the tune.
