Here is the version sung by the Sons of the Pioneers.   Obviously they were aiming at a family audience....

SHE CAME ROLLING DOWN THE MOUNTAINS
as sung by the Sons of the Pioneers

1
Down in West Virginia lived a gal named Nancy Brown
You never seen such beauty in the city or in town.
Nancy and the teacher climbed the mountainside one noon [preacher?]
They got up near the summit, but very very soon

She came rollin' down the mountains
She came rollin' down the mountains
She came rollin' down the mountains from above
For she left her bold companion
To the coyotes in the canyon
When the feller tried to tell 'er words of love.

2
She was sittin', knittin' woolen undies for her dad
When she saw a cowboy in his Sunday suit of plaid.
"How'd ya like to hike, dear," he remarked and raised his hat,
Again they climbed the mountains, but shortly after that

She came rollin' down the mountains
She came rollin' down the mountains
She came rollin' down the mountains high and wide
When he tried to get too pally
Nancy headed for the valley
For she wouldn't vow to be a cowboy's bride

3
Then a city slicker who had hundred dollar bills
Came ridin' in his auto to the West Virginia hills
Nancy looked him over, thinkin' "There's the man for me,"
She stepped into his roadster and the rest is history.

Oh she stayed up in the mountains
Oh she stayed up in the mountains
Oh she stayed up in the mountains [with delight] *
For that handsome city slicker
Made her girlish heart beat quicker
And her pappy chased poor Nancy out of sight.

* I always figured this was originally "til daylight."

4
Nancy and the slicker they were married right away,
She got a diamond bracelet on her happy weddin' day.
Though she's in the city she remembers now and then
The lovers who pursued her and the happy moments when
        
She came rollin' down the mountains
She came rollin' down the mountains
She came rollin' down the mountains by the stills
Oh her life is beer & skittles
And she's eatin' fancy victuals
And she owes it all to the West Virginia hills!
