Regarding that song,  Robert Katz has reminded of this:

From the movie Shenandoah:

Charlie Anderson: Can you give me one good reason why I should let my sons march down that road like a bunch of damn fools?
Lt. Johnson: Virginia needs all her sons, Mr. Anderson.
Charlie Anderson: They don't belong to the state they belong to ME! When they were babies I never saw the state comin' around here with a spare tit!

Charlie Anderson played by Jimmy Stewart.
