Lords and Ladies is a fantasy novel by British writer Terry Pratchett, the fourteenth Discworld book. It was originally published in 1992. Some parts of the storyline spoof elements of Shakespeare’s play A Midsummer Night’s Dream.
The song is perhaps best known for its opening lines: “Timothy Leary’s dead / No, n-n-no he’s outside looking in”, which allude to Leary’s use of eastern mysticism (most notably The Tibetan Book of the Dead) to frame the psychedelic experience.
