I found this verse to "My homes in Montana", in a school textbook, Silver Burdett & Ginn, Music3. It is presented as a partner song with "Home on the Range". Same chords, different melody, but work together when sung simultaneously

My homes in Montana I left Indiana
To start a new life far away in the West
My skins rough as leather, made tough by the weather
The wind and the sun of the land I love best

Chorus
Home, on the rolling range
That's were I want to stay
When ridding the ranges
My luck never changes
With foot in the stirrup
I gallop away
