Here's my attempt at transcribing the Cousin Jody recording:

UNPUCKER
(Charles and Ira Louvin and Bill Carlisle)

Now, I was only twenty three when I first met my love,
Freckle-faced and pig-tailed, she was my turtle dove;
One night upon the old settee, I popped the question low,
And when we both got puckered up, she softly whispered, "NO!"

CHORUS:
Unpucker, mama's at the door,
Unpucker, or we can't court no more;
Now, you know what'd happen if she saw us puckered up like this -
Unpucker, 'fore she gives that knob a twist.

I borrowed papa's Model A to take her for a ride,
To the drive-in movies where I thought that we could hide;
I found a place to park the car, turned on the radio,
And when we both got puckered up, she softly whispered, "NO!"

CHORUS:
Unpucker, mama's at the door,
Unpucker, or we can't court no more;
She's out there tryin' to help us 'cause she thinks we're out of gas;
Unpucker, she's a-peekin' through the glass.


One night I went to see her, it came a thunderstorm,
We didn't get to pucker up 'til it was nearly morn;
When to my luck the lightning struck and all the lights went out,
I puckered up and I grabbed her quick and then I heard her shout:

CHORUS
Unpucker the lights have come back on,
Unpucker, there must be something wrong;
....(don't get it), hey! that's Ma you're kissin' now!
Unpucker, 'fore you make that marriage vow.
