I have just filled in a few of the words in capitals that you were curious about, at least that was the way that I heard them.

Liberty Belle.

Repeat chorus

Came out to the USA in the year of '51.
If any OLD neighbours living here
Have seen or heard of him anywhere,
You'd oblige me if you'd help me find
My Uncle Dan McCann.

Well let me tell you about my Uncle Dan
BY GOD he was a mighty man,
HE Swam the River Liffey twice a day
He could run three ROUNDS of Phoenix Park,
Dance and sing just like a lark,
And he wasn't afraid to go home in the dark,
My Uncle Dan McCann.

So have you seen my Uncle Dan McCann?
Typical bit of a Galwayman,
Fought throughout the Civil War in the year of '61.
He was supple and nimble in every joint,
He wasn't afraid of the bayonet point,
He belonged to the FIGHTING 69th,
My Uncle Dan McCann.

Well I found my Uncle Dan McCann,
A VERY SUCCESSFUL YANKEE MAN,
He has a seat in Congress, and HE IS LEADER of his clan.
He HELPED to write America's laws,
But his heart and soul is in Ireland's cause,
God help the man who opens his jaws
To my Uncle Dan McCann.
