 Indeed, dedicated trance fans usually call it "happy hardcore" to indicate its "similar-but-different" nature.

The plays of L. Frank Baum are an important aspect of Baum's writing career about which some of the least is known.
 While even most brief biographies, long before the Internet, have noted Baum's work as a playwright, these works have been rarely performed beyond his lifetime, and almost none have been published aside from two scenarios and a first act of three unfinished works in "The Musical Fantasies of L. Frank Baum", compiled with an introduction by Alla T. Ford.
 Aside from his youthful success with "The Maid of Arran", his blockbuster eight-year run with "The Wizard of Oz", his failure with "The Woggle-Bug", and "The Tik-Tok Man of Oz" as source material for his novel, "Tik-Tok of Oz", very little is known about his dramatic output, and mostly from the publications of Michael Patrick Hearn, Susan Ferrara, and Katharine M. Rogers.
 Hearn identifies 41 different titles in the bibliography of the 2000 edition of "The Annotated Wizard of Oz", plus one play without a title, although some of these titles clearly refer to drafts of the same play, such as the early titles of "The Tik-Tok Man of Oz".
Adrift In Soho is a novel by Colin Wilson.
 It was first published in England in 1961 by Victor Gollancz.
 The novel describes the English beat generation.
 The novel was republished to great acclaim by New London Editions in 2011, when Cathi Unsworth wrote 'Adrift in Soho is currently in production by Burning Films and with such rich source material, perhaps Wilson will now receive some contemporary reassessment for his continuing fascination with the human condition and the wit, warmth and insight that he brings to his accounts of those he has shared his unusual journeys with.'
