It seems to be "Idaho," on Gene Autry's Cowboy Is A Patriot CD. But the singer is female.

The following is the Eddy Arnold version, from here.

Away beyond the hills in Idaho
where yawning canyons greet the sun
As it smiles above the trees in Idaho
to say another night is done
Warm summer winds toss a waving grain
calling me back to my home again
To dream sweet memories of long ago
beyond the hills in Idaho

(Away beyond the hills in Idaho)
where yawning canyons greet the sun
(As it smiles above the trees in Idaho)
to say another night is done
Warm summer winds...
(Away beyond the hill in Idaho)
