An on-shore revival in shanty singing for leisure was facilitated by song collections of the 1920s, especially Terry's "The Shanty Book" (in two volumes, 1921 and 1926). What set apart this and following collections was full musical score along with an adequate stock of lyrics. Collections prior to Terry's (except for Davis and Tozer's much earlier and contrived-sounding settings) had not provided enough verses to create "full" songs, and it is unlikely that performers would venture to improvise new verses in the manner of traditional shantymen. By 1926, it had become a custom at the Seven Seas Club in London to hold a shanty sing-along after the club's monthly dinners. By 1928, commercial recordings of shanties, performed in the manner of classical concert singing, had been released on HMV, Vocalion, Parlophone, Edison, Aco, and Columbia labels; many were realizations of scores from Terry's collection. Shanties like "Johnny Come Down to Hilo" were more or less standardized through popular dissemination.
