By John Nelson "Sleepy" Hall, Great Falls, Montana who sang his son, Neufy,(John Jr.) to rest with it.
Was given the title of Montana State Ballad, possibly 1940's-50's?
Lovely song.

THE GREEN HILLS OF MONTANA

The green hills of Montana
Are calling to me
I'm lonely
For my Rocky Mountain home.

The moonlight on the waters
The whispering trees
Are mem'ries
That will haunt me while I roam.

I'm gonna hit the road
With a heavy load
In my heart
But as the trail unwinds
And I smell the pines
My heart will get lighter
The trail will get brighter
The whole world will be mine

And the green hills of Montana
Will welcome me back
And my heart will rest
In my Rocky Mountain home.
