The next revival in shanties occurred as part of the Anglophone folk music revival of the mid-20th century. The American folk revival group The Almanac Singers were recruited by Alan Lomax to record several shanties for the 1941 album Deep Sea Chanteys and Whaling Ballads. In Britain, the incorporation of shanties into the folk revival repertoire was largely led by A.L. Lloyd starting in the 1950s. An amateur folklorist, Lloyd discarded the earlier classical style of presentations in favor of a more "authentic" performance style. He was generally mysterious about the sources of his shanty arrangements; he obviously referred to collections by editors like Sharp, Colcord, and Doerflinger, however it is often unclear when and whether his versions were based in field experience or his private invention. Lloyd's album "The Singing Sailor" (1955) with Ewan MacColl was an early milestone, which made an impression on Stan Hugill when he was preparing his 1961 collection, particularly as the performance style it embodied was considered more appropriate than that of earlier commercial recordings. Many other performers followed, creating influential versions and interpretations of shanties that persist today. For example, Lloyd's personal interpretation of "South Australia" was taken up by the Irish folk revival group The Clancy Brothers, from which this version spread to countless folk performers to become established as the "standard" form of what is usually presented as a "traditional" shanty. Through the mass distribution of particular shanty forms through recordings and clubs, the folk revival has had the effect of creating an impression of rather consistent forms of texts and tunes—a sharp contrast to the highly variable and often improvised nature of work-based shanty singing. Another effect, due to the fact that most folk performers sang shanties along with other genres, is that shanty repertoire was ever more incorporated within the generic fold of "folk song," and their distinctive use, manner of performance, and identity were co-opted.
