Terry's works were the source for those among the earliest of commercial recordings (see below) and popular performances of shanties—especially because, unlike many earlier works, they provided scores with piano accompaniment and sufficiently long, performance-ready sets of lyrics. Colcord's work was also very handy in this regard, and was used as a source by prominent British folk revival performers like A. L. Lloyd and Ewan MacColl. Terry and Colcord's works were followed by numerous shanty collections and scores that also chose to use the "sh" spelling, whereas others remained insistent that "ch" be retained to preserve what they believed to be the etymological origins of the term. By the late 20th century, the "sh" spelling had become the more or less standard one in Commonwealth English, whereas "ch" spellings remained in common use mostly in the United States.
