Wesley Stace is a British folksinger and author of four novels. You might not know his name as a musician, though, because most of his music is under the stage name John Wesley Harding. This was his debut single, from his debut album Here Comes The Groom.
The song, as the rest of the album, draws comparisons to Elvis Costello - and since a couple of The Attractions make up part of his backing band here, that's understandable. Lyrically, the song compares the attrocities of human behavior to, well, the devil. It is a brilliant and sardonic take on the subject.
