From Oklahoma! - the musical, not the state;

The farmer and the cowman should be friends.
Oh, the farmer and the cowman should be friends.
One man likes to push a plough, the other likes to chase a cow,
But that's no reason why they cain't be friends.

I'd like to say a word for the farmer,
He come out west and made a lot of changes...
He come out west and built a lot of fences,
And built 'em right across our cattle ranges.

There are lots of harvest and harvest home songs.

Then there is John Barleycorn. It was Ken Langsbury's brother who set the words to the tune of We Plough the Fields and Scatter.
