Can't remember when I learnt this but its a very long time ago. I think that a lot of the words were chosen so as to be alliterative.

Mary Mack

1.         
There's a fine wee lass
And her name's Mary Mack
Mak' no mistake
She's the lass I'm gonna tak'
There's a lot o' ither chaps
That would get upon her track
But I'm thinking that
They'd have tae get up early.

Chorus:        
Mary Mack's faither's making Mary Mack mairry me
My faither's makin' me mairry Mary Mack
I'm goin' tae mairry Mary
Tae get mairried and tak' care o' me
We'll a' be makin' merry when I mairry Mary Mack.

2.         
This wee lass,
She's got a lot o' brass
She has a lot o' gas,
Her faither thinks I'm class
And I'd be a silly ass
Tae let the maitter pass
Her faither thinks that
She would suit me fairly.

3.         
Noo Mary and her mither
Gang an awfy lot together
In fact ye never see the yin,
Nor the yin wi'oot the ither
An' the fellas offen wunner
If it's Mary or her mither
Or the baith o' them the gither
That I'm mairryin'

4.         
Noo the weddin' day's on Wednesday
And everything's arranged
Her name will soon be changed tae mine
Unless her mind be changed
Wi' makin' the arrangements, faith,
I'm just aboot deranged
For marriage
Is an awfy undertaking

5.         
It's sure tae be a grand affair
And grander than a fair
A coach and pair for rich and puir
And every pair that's there
We'll dine upon the finest fare,
I'm sure tae get ma share
If I don't
We'll a' be very much mistaken
