Wilf Carter, as Montana Slim, recorded WHEN THE SUN SAYS GOODNIGHT TO THE PRAIRIE [some sources say—incorrectly, I think—"...ON THE PRAIRIE"] on a 78-rpm record, Victor 27784-A, 1937, b/w COWBOY'S AIRPLANE RIDE.

Here's what I was able to transcribe from a sound sample:

...
The night-owl starts out on its flight.
You hear the lone call of the coyote
As he slinks through the valley or ...(?)
Painted pictures of gold
The range-land I'm told
When the sun says goodnight to the prairie....


It's possible Carter was inspired by the Pease/Vincent song, but if so, he has changed the tune considerably, for one thing, making it a waltz.
