The schools project also explains Sharp's bowdlerisation of some of the song texts, which, at least among English folk songs, often contained erotic double entendres, when not outright bawdy or violent. However, Sharp did accurately note such lyrics in his field notebooks, which, given the prudery of the Victorian era could never have been openly published (especially in a school textbook context), thus preserving them for posterity. An example of the transformation of a formerly erotic song into one suitable for all audiences is the well-known "The Keeper." The immediate goal of Sharp's project – disseminating the distinctive, and hitherto little known "melodies" of these songs through music education – also explains why he considered the song texts relatively less important.
