The Liberty Song

Who said this? What is the origin? Eishenhower spoke quite a bit about unification, but, this is more about cohesion, freedom, etc. Was subject of a song in the late 60's. Any ideas?

"United we stand, divided we fall" is the motto of the great Commonwealth of Kentucky. And it says on the state Web site: "The motto is believed to be from 'The Liberty Song,' popular during the American Revolution, and a favorite of Isaac Shelby, Kentucky's first governor."
