kind of song. The American song collection of over 200 songs in Hard Hitting Songs For Hard Hit People by Woody Guthrie, Pete Seeger and Alan Lomax in the 1940s (not published till 1967), explored worker's song further. The work of labour historian Archie Green, which included the production of recordings of labour and work songs, provided a wider context for understanding industrial folk song within a wider field of 'labor lore'. Songs written by Seeger and Guthrie, were also important in continuing the tradition and moving it into progressive folk music. Among the most successful of these composed industrial songs was Merle Travis' Sixteen Tons, first recorded in 1946, but made probably the most commercially successful industrial song when it was a major hit for 'Tennessee' Ernie Ford in 1955. In Britain the leading proponent of, and commentator on, industrial folk music was A. L. Lloyd. His Come All Ye Bold Miners: Ballads and Songs from the Coalfields, a collection of mining songs was published in 1952. Of his own recordings the most influential were his arrangement of various industrial songs on the LP The Iron Muse: a Panorama of Industrial Folk Song (1963). A. L. Lloyd wrote in the 1965 Encyclopædia Britannica a paragraph on 'Industrial Song', part his broader entry on 'Folk Music' and his Folk Song in England (1967) concluded with a chapter titled 'Industrial Folk Song', which popularised the term. Subsequently, David Harker criticised Lloyd for his romanticisation of industrial workers. The other major figure of the second British folk revival, Ewan MacColl also played a significant part in popularising British Industrial folk song, making Shuttle and Cage a 10" LP with Peggy Seeger for Topic Records in 1958 and alone an LP for Stinson in 1963 called British Industrial Folk Songs. From 1957 to 1964 probably the widest audience for British work songs was achieved through the Radio Ballads, of MacColl and Peggy Seeger, many of which focused on work, including rail workers, road building, fishing and coal mining. However, many of the songs in the Radio Ballads were written by MacColl himself in the style of the songs that he, Lloyd and others had collected e.g. 'Shoals of Herring'. In the British folk rock movement of the 1970s industrial folk music was less prominent than traditional ballads, but largely accepted as part of folk music, with songs like 'Blackleg Miner' being recorded beside
