THE American folk song Rock Island Line first emerged in the late 1920s, although the first recorded performance of the track wasn’t until 1934, by inmates of the Arkansas Cummins State Farm prison. After several covers, Lonnie Donegan’s fast-tempo recording of the song about a train operator who smuggles pig iron through a toll gate on the Chicago, Rock Island and Pacific Railroad was released in late 1955. Donegan’s work was a major influence on Paul McCartney, John Lennon, George Harrison and many others, and it is credited with helping to trigger the UK skiffle craze. Presented by Billy Bragg.
