This is the first poem out of two featuring the Man in the Moon in this book. There are only two minor differences between this version and the one featured in The Lord of the Rings. An original version can be read in The Return of the Shadow. A revision of that one was published in Yorkshire Poetry in 1923 as The Cat and the Fiddle: A Nursery-Rhyme Undone and Its Scandalous Secret Unlocked. The poem or song is written by Bilbo Baggins.
Inspired by the time one of J.R.R. Tolkien's son lost his toy dog, the tale of Rover, a young dog that will have lots of adventures after upsetting a wizard.
