This is my transcription of the lyrics to that song.
As usual I am unsure about some part of it (marked in red).

DUCKS OF MAGHERALIN

[spoken]
This next song was written to disprove the popular rumour that Dublin is the capital of Ireland

Oh well just a year ago today
I went to see the queen
She wrapped me up in satin
And its colour it was green
She decked me out in medals
And they were all made of tin
Oh said she go home you critter
You're the mayor of Magheralin

Chorus


[VC*]

Last time repeat last two lines starting with "And" instead of "Yes".

Oh what is the finest city
In a real old fashioned style
A credit to sweet county Down
The pride of the emerald isle
It has the finest harbour
For the red coats to sail in
And if ever you sail to Ireland
You'll sail by Magheralin

Oh you've all heard of Napoleon
Napoleon Bonaparte
He conquered half of Europe
But left the older parts
He tried to conquer Ireland
But they would not give in
And he died in Saint Helena
When he thought of Magheralin

Oh you've heard of Cleopatra
The treasure of the Nile
And how she conquered Tony
With one adoring smile
She tried to conquer Ireland
But they would not give in
And they beat her rife with cabbage
Leased from the town of Magheralin

Oh you've heard of good king William
King William crossed the Boyne
With a hundred thousand balls of wax
And a thousand balls of twine
And then he gave the order
For the cobblers to begin
For to make a thousand pairs of boots
For the ducks of Magheralin

Oh you've heard of Mussolini
That great Italian bum
And how his troops in Africa
Were always on the run
You've heard of Winston Churchill
He always wore a grin
For he knew the Ulster rifles
Was all born in Magheralin
