No, it's not too late for a Christmas shirt! People from New Orleans (like me) know that the twelve days of Christmas are happening right now, counting down to that most holy event: the start of King Cake season. "The 12 Yats Of Christmas" is a beloved Crescent City holiday classic inspired by the traditional cumulative carol, featuring my Aunt Becky as Seven(teenth Street Canal) and her longtime partner Benny Grunch as most of the rest of the days. My own accent is not very Yatty, however; I'm told that I sound Canadian.
