Question:
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."

Answer the question at the end by quoting:

MC5 was an American rock band from Lincoln Park, Michigan, formed in 1964. The original band line-up consisted of vocalist Rob Tyner, guitarists Wayne Kramer and Fred "Sonic" Smith, bassist Michael Davis, and drummer Dennis Thompson. "Crystallizing the counterculture movement at its most volatile and threatening", according to AllMusic critic Stephen Thomas Erlewine, the MC5's leftist political ties and anti-establishment lyrics and music positioned them as emerging innovators of the punk movement in the United States.
The origins of MC5 can be traced to the friendship between guitarists Wayne Kramer and Fred Smith. Friends since their teen years, they were both fans of R&B music, blues, Chuck Berry, Dick Dale, The Ventures, and what would later be called garage rock: they adored any music with speed, energy and a rebellious attitude. Each guitarist/singer formed and led a rock group (Smith's Vibratones and Kramer's Bounty Hunters). As members of both groups left for college or straight jobs, the most committed members eventually united (under Kramer's leadership and the "Bounty Hunters" name) with Billy Vargo on guitar and Leo LeDuc on drums (at this point Smith played bass), and were popular and successful enough in and around Detroit that the musicians were able to quit their day jobs and make a living from the group. Kramer felt they needed a manager, which led him to Rob Derminer, a few years older than the others, and deeply involved in Detroit's hipster and left-wing political scenes. Derminer originally auditioned as a bass guitarist (a role which he held briefly in 1964, with Smith switching to guitar to replace Vargo and with Bob Gaspar replacing LeDuc), though they quickly realized that his talents could be better used as a lead singer: Though not conventionally attractive and rather paunchy by traditional frontman standards, he nonetheless had a commanding stage presence, and a booming baritone voice that evidenced his abiding love of American soul and gospel music. Derminer renamed himself Rob Tyner (after Coltrane's pianist McCoy Tyner). Tyner also invented their new name, MC5: it reflected their Detroit roots (it was short for "Motor City Five'). In some ways the group was similar to other garage bands of the period, composing soon-to-be historic workouts such as "Black to Comm" during their mid-teens in the basement of the home of Kramer's mother. Upon Tyner's switch from bassist to vocalist, he was initially replaced by Patrick Burrows, however the lineup was stabilised in 1965 by the arrival of Michael Davis and Dennis Thompson to replace Burrows and Gaspar respectively. The music also reflected Smith and Kramer's increasing interest in free jazz--the guitarists were inspired by the likes of Albert Ayler, Archie Shepp, Sun Ra and late period John Coltrane, and tried to imitate the ecstatic sounds of the squealing, high-pitched saxophonists they adored. MC5 even later opened for a few U.S. midwest shows for Sun Ra, whose influence is obvious in "Starship". Kramer and Smith were also deeply inspired by Sonny Sharrock, one of the few electric guitarists working in free jazz, and they eventually developed a unique interlocking style that was like little heard before: Kramer's solos often used a heavy, irregular vibrato, while Smith's rhythms contained an uncommon explosive energy, including patterns that conveyed great excitement, as evidenced in "Black to Comm" and many other songs.
