Anyway, a couple of fans of Belloc's poetry include J.K. Rowling (author of the Harry Potter series) and Syd Barrett (of Pink Floyd).
Rowling, for instance, contributed Belloc's poem "Jim Who Ran Away From His Nurse and Was Eaten By Lion" to a book called Once Upon a Poem: Favourite Poems That Tell Stories. [Source] As Rowling states:
As for Syd Barrett, this link discusses Barrett's love of Bellocs "Cautionary Tales for Children", and also discusses the original version of the song "Matilda Mother" (based on Belloc's poetry), which, as the link describes it, "helped give the band their start"
I should perhaps point out that I do not read Harry Potter, nor have I ever listened to Pink Floyd. As for Belloc, while I have read "Cautionary Tales for Children", the other books I have read by him mainly deal with the history of the Catholic Church. That said, I did wish to make this post (which I've been meaning to) before I forgot to again. :-)
