AH'M FEAR'D FOR MRS. McKIE
As sung by Will Fyffe

If ye'd seen me before I got married,
You would have said, "There's a man,"
But just like the rest I was captured,
And then all my troubles began;
For the boss of the hoose is the missus,
An I sometimes myself have to laugh,
For though I'm six foot three, she's the boss over me
And she's only four foot and a half.
Still I'm feart for Mrs McKie.
I'm feart for Mrs McKie.
When I'm oot wi ma mates, I don't care a hang.
When I land at the hoose, I'm as quiet as a lamb,
'Cause I'm feart for Mrs McKie,
And when I take a dram on the sly,
I pit a peppermint drap in ma mooth
'Cause I'm feart for Mrs McKie.

There's a lass at the fit o the vennel(?).
She works in a wee sweetie shop.
Sometimes when I keek through the windae,
She winks and invites me ta stop
And suggests we should go to the pictures
Or that I take her oot on the sly,
And sometimes I think I would like to, but mind ye,
I think o Mrs McKie,
'Cause I'm feart for Mrs McKie.
I am feart for Mrs McKie,
For in oor but-an-ben she rules like a queen.
If I'm five minutes late she says, "Whaur hae ye been?"
And I've got the neebours ta think o,
For they're aye peepin oot on the sly,
So the lassie can bide in her wee sweetie shop
'Cause I'm feart for Mrs McKie.

Ye would think that ma wife was a hero
The way that she bosses the hoose.
There's only one thing that she's feard o,
And that's just a tiny wee moose.
She woke me at three in the mornin
And said, "There's a moose in the trap.
Do ye think ye could manage to kill it, my darlin?
Mon, ye're a brave little chap!"
An I'm feart for Mrs McKie.
I am feart for Mrs McKie
So I got intae bed, I turned oot the licht
While Maggie was under the claes i the sicht(?).
I said, "Now I'll show Mrs McKie."
I said to mysel, "Do or die!"
So I rolled up ma sleeves an I strangled the moose.
Still I'm feart for Mrs McKie.

[PATTER OMITTED]

I'm feart for Mrs McKie.
I'm feart for Mrs McKie.
When I'm oot wi ma mates, I don't care a hang.
When I land at the hoose, I'm as quiet as a lamb,
'Cause I'm feart for Mrs McKie,
And when I take a drink on the sly,
I shove a peppermint drap in ma mooth
'Cause I'm feart for Mrs McKie.
