In the children's storybook "Chanticleer and the Fox", Barbara Cooney retells The Nun's Priest's Tale, using her own illustrations. Published in 1958, it was the recipient of the Caldecott Medal for illustration in 1959. Its robust confrontation of the problem of good and evil was considered as challenging for younger readers. Among other works that were created specially for children there was "Chanticleer and the Fox", a musical play based on the Nun's Priest's Tale, in which the collaborators were the composer of light music Edward Hughes and the poet Peter Westmore (Oxford 1966). It was followed by Michael Hurd's "Rooster Rag", a 13-minute pop cantata for narrator and unison voices that was commissioned and first performed in May 1975 at the Cookham Festival. The main chorus is of six hens, and there are the solo characters of Chanticleer, Pertelote and Mr Fox for stage versions. The choice of title was influenced by the popular "Chanticleer Rag" of 1910. However, the original cover illustration for that (based on a costume design by Coquelin) and the words make it clear that its inspiration was Edmond Rostand's drama "Chantecler" about a cock that believed the sun would not rise unless it crowed first.
