Grand Ole Opry connection

Mammoth Spring is credited with providing the original inspiration to George D. Hay to create what became the Grand Ole Opry in Nashville.^[12] Hay was sent on a reporting assignment to Mammoth Spring in 1919 when he was invited to a hoedown in a local cabin.^[12] There, a fiddle player, a guitar player, and a banjo player performed until dawn.^[12] Hay was impressed, and that planted the seed for his later efforts.^[12]
