Except none of the song alludes to anything frontierish in that manner.
Here's the intro:
Howdy folks! Welcome to the one and only, original, Country Bear Jamboree — featuring a bit of Americana, our musical heritage of the past
But there aren't any songs from the past. No songs about wagon trains or railroads or the wild frontier. Instead, gems like this...
One night, I left the wife at home,
And I went out with the boys.
I was acting like a Don Juan,
And making a lot of noise.
ZEKE
Tell ’em, lover boy!

A go-go girl caught my hand,
I said, “I can’t. I’m a married man.”
She said “If you ain’t gonna steal,
You better not prowl.”
Go-go dancer? That's a 19th century turn of phrase?
The problem with MK's Frontierland is that it confuses "Southern" with "Frontier."
