The Introduction presents an overview of the topic of street song and summarizes the main chapters of the book. It begins by discussing poems by Robert Herrick and Thomas Campion based on the traditional street-vendor’s cry of ‘Cherry Ripe’ as an example of the way in which writers appropriate street songs for their own purposes, and includes discussions of other images and texts such as Donald Davie’s poem ‘Cherry Ripe’. ‘Cherrie-ripe’ traces an arc from the sixteenth century to the twentieth, encompassing literature, art, music, and social history. It suggests the broad scope of the subject, but although attention is paid to its rich and varied contexts, the focus of this book is on the ways in which street song has found its way into works of literature.
