Notes: A dun horse is a yellow brown one with a black stripe down its back - some of them sort of go back to their wilder roots and have black stripes on their legs as well and they are called Zebra Dun.
Here?s a wonderful cowboy ballad I learned from Dwayne Thorpe. It?s called the Zebra Dun (that?s the kind of horse this bucking bronco was). The song mentions a couple of railroads: the Santa Fe usually known as the Santa Fe, and the Old S.P. or Southern Pacific.
