Hi CB ... I would suspect that this person who invited you perhaps has fine intentions but maybe doesn't have a clue as to the historical definition of the term. Over the years, I've run into a lot of "hootenanny wannabees," meaning people who perhaps saw a bad TV show, or a bad movie, and decided that they could do it better. So at this point, it's strictly up to your good graces and your perception of proper manners. Are you a performer? If so, look out, as this person might be expecting you to perform ... for free ... into a plan you know nothing of. Just trying to be helpful! CHEERS, Bob
