The first music inspired by his work was written by the English songwriting team of Donald Swann and Michael Flanders, who set poems from "The Hobbit", "The Lord of the Rings" and other works to music and included them in their 1963 revue "At the Drop of a Hat". When an interviewer called Swann "elfin", he said, "Yes, and in the show, I sing in Elvish!" In 1970, Swedish keyboardist Bo Hansson recorded "Music Inspired by 'Lord of the Rings'", becoming the first in a series of pop artists to do so for the rock-oriented market.
