YouTube has a video of this song (called WHEN PA WAS COURTING MA) performed by a very young-looking Lawrence Welk and his orchestra. (He doesn't sing or speak but plays the accordion.) The vocalists are, I think, Lois Best & Parnell Grina. Here's my transcription:

WHEN PAW WAS COURTIN' MAW
Words, Jack Manus. Music, Leonard Joy. 1938

We asked our Paw where did they go
When folks went courtin' years ago,
With no amusements like we have today.
Oh, the radio was then unknown.
They just had grandma's gramophone,
But still they fell in love and life was gay.

They didn't have no airy-planes,
Didn't have no streamlined trains,
But they had lonely country lanes
When Paw was courtin' Maw.

They didn't have no ritzy bars,
Fancy drinks and caviars,
But they had lots of moon and stars
When Paw was courtin' Maw.

Well, they did have fun; they didn't miss a single husking bee.
Then comin' home they'd sneak a kiss, and Paw'd say "Gosh!" and Maw'd say "Gee!"

Most important thing somehow,
They all knew, for you'll allow,
Love was love the same as now
When Paw was courtin' Maw.

The bustle that you often wear,
The flowers in your pretty hair
Are so much like what made them stare
When Paw was courtin' Maw.

Now, say, you think you look your very best
In that checkered suit and that fancy vest.
Well, it seems to me that's how they dressed
When Paw was courtin' Maw.

Honey, if we had met in Pappy's time, how different would we talk?
Well, sweet nothings must truly sound alike to the square dance or the Lambeth walk.

"I love you" are the words we say,
And so they were in Pappy's day.
They did it in the same old way
When Paw was courtin' Maw.
