This song was written by bandleader Erskine Hawkins, Julius Dash, and William Johnson. The latter two were saxophone players with Hawkins. The title of the song comes from an actual railroad junction in Alabama. Miller and Hawkins both appeared at the Savoy Ballroom in Harlem on Christmas Eve 1939. Hawkins played the tune and members of the Miller band took notice. Jerry Gray wrote up an arrangement a few days later and the Miller band recorded the song in 1940, to great success.
