Answer the question at the end by quoting:

Michael John Harrison (born 26 July 1945), known for publication purposes primarily as M. John Harrison, is an English author and literary critic. His work includes the Viriconium sequence of novels and short stories (1971-1984), Climbers (1989), and the Kefahuchi Tract trilogy, which consists of Light (2002), Nova Swing (2006) and Empty Space (2012). He is widely considered one of the major stylists of modern fantasy and science fiction, and a "genre contrarian". The Times Literary Supplement described him as 'a singular stylist' and the Literary Review called him 'a witty and truly imaginative writer'.
Harrison was born in Rugby, Warwickshire, in 1945 to an engineering family. His father died when he was a teenager and he found himself "bored, alienated, resentful and entrapped", playing truant from Dunsmore School (now Ashlawn School). An English teacher introduced him to George Bernard Shaw which resulted in an interest in polemic. He ended school during 1963 at age 18; he worked at various times as a groom (for the Atherstone Hunt), a student teacher (1963-65), and a clerk for the Royal Masonic Charity Institute, London (1966). His hobbies included electric guitars and writing pastiches of H. H. Munro.  His first short story was published during 1966 by Kyril Bonfiglioli at Science Fantasy magazine, on the strength of which he relocated to London. He there met Michael Moorcock, who was editing New Worlds magazine. He began writing reviews and short fiction for New Worlds, and by 1968 he was appointed books editor. Harrison was critical of what he perceived as the complacency of much genre fiction of the time. During 1970, Harrison scripted comic stories illustrated by R.G. Jones for such forums as Cyclops and Finger. An illustration by Jones appears in the first edition of Harrison's The Committed Men (1971).  In an interview with Zone magazine, Harrison says "I liked anything bizarre, from being about four years old. I started on Dan Dare and worked up to the Absurdists. At 15 you could catch me with a pile of books that contained an Alfred Bester, a Samuel Beckett, a Charles Williams, the two or three available J. G. Ballards, On the Road by Jack Kerouac, some Keats, some Allen Ginsberg, maybe a Thorne Smith. I've always been pick 'n' mix: now it's a philosophy."

His father died when he was a teenager

Some context: Chapter 27 is a 2007 biographical drama film depicting the murder of John Lennon by Mark David Chapman. It was written and directed by Jarrett Schaefer, based on the book Let Me Take You Down by Jack Jones, produced by Robert Salerno, and stars Jared Leto as Chapman. The film takes place in December 1980, and is intended to be an exploration of Chapman's psyche. Its title is a reference to J. D. Salinger's novel The Catcher in the Rye, which has twenty-six chapters, and suggests a continuation of the book.
The real Mark David Chapman is currently incarcerated at Wende Correctional Facility, on a guilty plea. Aside from two interviews with Larry King and Barbara Walters, both in 1992, he has not spoken with the media. However, Chapman did reveal the mechanics of his unraveling during those three days in New York City to journalist Jack Jones. The interviews were published in 1992 as Let Me Take You Down: Inside the Mind of Mark David Chapman, a book of Chapman's recollections of his act of violence. Chapter 27 is based on this text. The title "Chapter 27" suggests a continuation of J. D. Salinger's novel The Catcher in the Rye, which has twenty-six chapters, and which Chapman was carrying when he shot John Lennon. Chapman was obsessed with the book, to the point of attempting to model his life after its protagonist, Holden Caulfield.  According to the British music magazine Mojo, the title was also inspired by Chapter 27 of Robert Rosen's book Nowhere Man: The Final Days of John Lennon (2000). Rosen's book explores the numerological meaning of the number 27, "the triple 9", a number of profound importance to John Lennon. Lennon was deeply interested in numerology, particularly Cheiro's Book of Numbers, along with nine and all its multiples. It was Chapman's goal, according to Rosen, to write Chapter 27 "in Lennon's blood".  Like Chapman, Schaefer is a fan of both The Beatles and J.D. Salinger's novel The Catcher in the Rye, and said he began the script to try to understand "how someone could be inspired to kill anyone as a result of being exposed to this kind of beautiful art. It really bothered me, because Lennon and Salinger have always made me feel so much better, and so much less alone."

IN: Sia Kate Isobelle Furler (; born 18 December 1975) is an Australian singer-songwriter, record producer and music video director. She started her career as a singer in the local Adelaide acid jazz band Crisp in the mid-1990s. In 1997, when Crisp disbanded, she released her debut studio album titled OnlySee in Australia. She then moved to London, England, and provided lead vocals for the British duo Zero 7.

After Crisp disbanded in 1997, Sia moved to London, where she performed as a background vocalist for British band Jamiroquai. She also provided lead vocals for English downtempo group Zero 7 on their first three studio albums and toured with the group. On Zero 7's 2001 album Simple Things, Sia contributed vocals to two tracks: "Destiny" and "Distractions." The single "Destiny" peaked at No. 30 on the UK Singles Chart. In 2004, she provided vocals for Zero 7 on "Somersault" and "Speed Dial No. 2" (from the album When It Falls). In 2006, Sia again collaborated with Zero 7 for the group's third album, The Garden and hence she is regarded as the "unofficial" lead singer of Zero 7.  In 2000, Sia signed a recording contract with Sony Music's sub-label Dance Pool and released her first single, "Taken for Granted", which peaked at No. 10 on the UK Singles Chart. In 2001, she released her second solo album, Healing Is Difficult, which blends retro jazz and soul music and lyrically discusses Sia's dealing with the death of her first love affair. Displeased with the promotion of the album, Sia fired her manager, left Sony Music and signed with Go! Beat, a subsidiary of Universal Music Group (UMG). At the APRA Awards of 2002, Sia won the Breakthrough Songwriter category alongside Brisbane pop duo Aneiki's Jennifer Waite and Grant Wallis.  In 2004, Sia released her third studio album, Colour the Small One. The album employs a mixture of acoustic instruments and electronic backing to her material. The album spawned four singles: "Don't Bring Me Down", "Breathe Me", "Where I Belong" and "Numb". "Breathe Me" peaked at No. 71 in the United Kingdom, No. 19 in Denmark and No. 81 in France. "Where I Belong" was scheduled to be included on the soundtrack for the film Spider-Man 2; however, owing to a record label conflict, it was withdrawn at the last minute.  Dissatisfied with Colour the Small One's being poorly marketed and struggling to connect with a mainstream audience, Sia relocated to New York City in 2005. During that time, "Breathe Me" appeared in the final scene of the U.S. HBO television series Six Feet Under, which helped increase Sia's fame in the United States. Consequently, Sia's manager, David Enthoven, set up a tour across the country to maintain her career.
