John Hilton's "Catch That Catch Can" is described as "A choice collection of Catches rounds and canons". Inside there is a table of "catches and rounds in this book", followed by "a table of the Sacred Hymns and Canons"; however, none of the first section is specifically described as catch or round. In the last section the canons are described as such, and the few "hymns" in three parts have no description; in fact unlike the catches and canons they are very much older than the rest of the contents which had been written in the first half of the seventeenth century.
