DeFord Bailey, an influential African American harmonica player, was among the Grand Ole Opry’s earliest and most celebrated performers. His first documented appearance on WSM radio’s Barn Dance, the precursor to the Grand Ole Opry, was on June 19, 1926. On December 10, 1927, during a broadcast following a classical music program, WSM station manager George D. Hay introduced Bailey, who performed his signature “Pan American Blues.” It was during this broadcast that Hay famously remarked, “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.'” This moment marked the inception of the show’s enduring name, with Bailey’s performance playing a pivotal role. ?Wikipedia

Bailey’s innovative harmonica techniques and captivating performances earned him the moniker “Harmonica Wizard.” He remained a prominent figure on the Grand Ole Opry until 1941, sharing the stage with notable artists such as Uncle Dave Macon, Bill Monroe, and Roy Acuff. His contributions were instrumental in shaping the early sound of the Opry and in breaking racial barriers within the country music scene.
