Not exactly a lullaby to calm a herd down. Also written and recorded by Stan Smith in 1948, way after the era of cattle drives had ended.
In the 90’s I would see cowboys moving cattle around small towns as the train passed thru. But that’s much different from having to spend the night with them. I have a photograph from my grandmother’s Colorado ranch that shows an old type car where the side of the car folded down into a shelf/table and the side was filled with cans and utensils, much like a chuckwagon. There’s one photograph of father’s stepfather watering his horse at the watering hole, so horses were still used there around 1910.
