Question: Who is a founding member of Joy Division, Peter Cox or Bernard Sumner?
Context: Control is a 2007 British biographical film about the life of Ian Curtis, singer of the late-1970s English post-punk band Joy Division.  It is the first feature film directed by Anton Corbijn, who had worked with Joy Division as a photographer.  The screenplay by Matt Greenhalgh was based on the biography "Touching from a Distance" by Curtis's widow Deborah, who served as a co-producer on the film.  Tony Wilson, who released Joy Division's records through his Factory Records label, also served as a co-producer.  Curtis' bandmates Bernard Sumner, Peter Hook, and Stephen Morris provided incidental music for the soundtrack via their post-Joy Division incarnation New Order.  "Control" was filmed partly on location in Nottingham, Manchester, and Macclesfield, including areas where Curtis lived, and was shot in colour and then printed to black-and-white.  Its title comes from the Joy Division song "She's Lost Control", and the fact that much of the plot deals with the notion that Curtis tried to remain Peter Cox is the debut solo album from Go West frontman Peter Cox.  It features 11 tracks mostly written by Cox and album producer Peter-John Vettese. Peter John Cox (born 17 November 1955) is an English singer-songwriter, best known as the lead singer of the British pop duo Go West. "Doubts Even Here" is the seventh track of eight on New Order's debut album "Movement", released on November 13, 1981.  After the death of Joy Division singer Ian Curtis, the surviving members formed New Order with drummer Stephen Morris's girlfriend Gillian Gilbert joining five months later.  This led to a dispute over who should fill Curtis' shoes with the lead vocalist role.  All three male members were in contention, but due to Bernard Sumner's voice being significantly different from Curtis', New Order opted for him to take the role, wanting New Order's sound to be different from Joy Division's.  Ironically with this new vocalist, in addition to "Doubts Even Here", the first track ("Dreams Never End") on the first album recorded by New Order, "Movement", is sung by bassist Peter Hook with spoken contributions by Gillian Gilbert, reading from the Bible.  The lyrics were written by Stephen Morris. "New Dawn Fades" is a song from the 1979 album "Unknown Pleasures" by Joy Division.  It opens with a backwards and heavily modified sample from previous song "Insight", presumably added by Martin Hannett, post-production.  The song relies on an ascending guitar riff by Bernard Sumner played against a descending bass riff by Peter Hook.  The song uses the same progression throughout, but grows in intensity as the song progresses, reaching its peak with Ian Curtis singing "Me, seeing me this time, hoping for something else", and ending with a guitar solo.  The song closes side one of "Unknown Pleasures".  It's also one of few Joy Division songs with two distinct guitars playing, one distorted and one a clean electric guitar picking notes from the guitar chords.
