I must admit I have never heard the term 'Kentuckiana'. I figured Jack just made a mistake in spelling Kentuckian, but since Jack so seldom makes mistakes I decided to do a dictionary search. Much to my surprise there is a word 'Kentuckiana', used in the border areas of Kentucky and Indiana where they have a county that is within each state.
A new word for me to remember.
Wish I could go to the show but it is a bit far to travel for me.
