In 1927, Hay spontaneously renamed the Barn Dance while introducing some of his down-home musicians on a WSM weekday evening broadcast following a classical music program. Countering the view that "there is no place in the classics for realism," Hay said, "[W]e will present nothing but realism. It will be down to earth for the 'earthy.'" As if to illustrate his point, Hay introduced Bailey, whose "Pan American Blues" recreated the whoosh of the L&N Railroad express train he had heard from his boyhood. In his introduction, Hay also said, "For the past hour, we have been listening to music largely from Grand Opera, but from now on, we will present 'The Grand Ole Opry.'" Thus Bailey and his musical cohorts helped to inspire the name of America's longest-running radio show.
