If you are getting state or federal money to put on a performance, I would hope that songs are not put in a performance intended to insult one side or the other, but to honor those who fought on either side..brother against brother, father against son in the border states. Ancestor against ancestor. Singing combined with smugness is not a pleasant combination. Singing combined with some sort of humbleness, as in there but for the grace of God go I, is, it seems to me anyway.
