Last week, the New York Times reported a piece on the similarities between those dedicated fans of Wagner's four-opera "Ring des Nibelungen" and our own die hard Cub fans. Turns out, even Plácido Domingo was talking about the many years of frustration suffered by longtime Cub fans. The tie between the opera and baseball has been studied for ages; with Chicago seeming to have a more intense connection than other places like NYC. Domingo even offered up a request, to sing the national anthem if the Cubs make the playoffs. It would mark his first visit to Wrigley Field.
