Here's one version.

My grandmother she, at the age of eighty three,
One day took sick and died;
And after she was dead, the will, of course, was read,
By a lawyer as we all stood side by side.
To my brother it was found she had left one hundred pound,
The same unto my sister, I declare;
But when it came to me, now the lawyer said, "I see,
She has left you her old armchair."

How they tittered, how they chaffed,
How me brothers and me sisters laughed,
When they heard the lawyer declare,
"Grannie's only left you her old armchair."

I thought it hardly fair but still I didna care,
And in the evening took the chair away;
The neighbours at me laughed and me brother at me chaffed,
And said, "It will be useful some day.
When you settle down in life, find a girl to be your wife,
You'll find it very handy, I declare;
On a cold and frosty night, when the fire burns bright,
You can sit in your old armchair."

My brother's words come true, for within a year or two,
I had settled down in married life;
I first the girl did court and then the ring I bought,
Then I took her to the church tae be my wife.
Oh the old gal and me were as happy as could be,
For when my work was over, I declare,
I was never one to roam, but each night stayed at home,
And was seated in my old armchair.

One night the chair fell down, when I picked it up I found,
The seat had fallen out upon the floor;
And there to my surprise, I saw before me eyes,
A lot of gowd, ten thousand pounds, or more.
When my brother heard of this, the fellow, I confess,
Went nearly wild with rage and tore his hair;
I only laughed at him and said unto him, "Jim,
Don't you wish you had the old armchair?"

How they tittered, how they chaffed,
How me brothers and me sisters laughed,
When they heard the lawyer declare,
"Grannie's only left you her old armchair."
