Here are the words you wanted:

PAT MOLLOY

Pat Molloy was an Irish boy. He left the County Clare.
He said he'd go to London for to see what sites were there.
He often heard that London was a very pretty place.
"Well, begod!" says Pat, "I'll go there so, to see if that's the case."

CHORUS:
Rally ra da diddle di do right fal de de.

But when he got to London, well, he had a big surprise,
For the sight of that great city nearly dazzled Paddy's eyes.
One day as he's going down the street, meditating to himself,
He spied a ragged Cockney and a donkey selling Delft.
CHORUS

Now the damned auld ragged Cockney wouldn't let poor Paddy pass,
Saying, "Speak unto your brother," and he pointed to the ass.
"Begod!" says Pat. "I never thought I had a brother here."
And turning round, he whispered something in the ass's ear.
CHORUS

Now when speaking to the donkey, well, boys, what did he do?
He slipped a pebble in his ear. He did, begod! 'Tis true.
The ass went mad, upset the cart, broke all the earthen ware,
And the damned auld ragged Cockney, he went crazy clean and clear.
CHORUS

Well, the police they were called for to put poor Pat in charge,
Saying, "Apprehend this vagabond. He should not be at large."
"Begone, you English spailpin, then," says Paddy with a smile.
"You thought I was an ass because I came from Eireann's isle."
CHORUS

"That's nonsense," said the magistrate, "for you know the ass went mad."
"I do indeed, Your Honor, and I'm sorry too, bedad!"
"Be careful," said the magistrate. "I want no nonsense here.
Now come and tell me everything you whispered in his ear."
CHORUS

"I will indeed, Your Honor. Your request I'll not refuse,
For you often heard that donkeys are very fond of news.
I thought I say a word or two, the donkey's heart to cheer,
And now I'll tell you everything that I whispered in his ear.
CHORUS

"They say that now in Ireland we have our wrongs redressed.
Our noble-hearted Irishmen no longer are oppressed.
We've got rid of all our landlords. Ireland to ourselves we have.
And when the donkey heard the news, well bejesus! He went mad."
CHORUS

The magistrate from laughing, he had to creep his head
When he looked on dear auld Paddy and the things that he had said.
And turning round to Paddy, "What a clever boy you are!
And for your clever answer, I'll dismiss you from the bar."
CHORUS
