Question: Moss was born in London, son of Alfred Moss, a dentist of Bray, Berkshire, and Aileen (nee Craufurd). He was brought up at Long White Cloud house on the right bank of the River Thames. His father was an amateur racing driver who had placed 16th at the 1924 Indianapolis 500. Stirling was a gifted horse rider as was his younger sister, Pat Moss, who became a successful rally driver and married Erik Carlsson.

Although ostensibly retired from racing since 1962, Moss did make a number of one-off appearances in professional motorsport events in the following two decades. He also competed in the 1974 London-Sahara-Munich World Cup Rally in a Mercedes-Benz, but retired from the event in the Algerian Sahara. The Holden Torana he shared with Jack Brabham in the 1976 Bathurst 1000 was hit from behind on the grid and eventually retired with engine failure. Moss, at the wheel of the Torana when the V8 engine let go, was criticised by other drivers for staying on the racing line for over  2/3  of the 6.172 km long circuit while returning to the pits as the car was dropping large amounts of oil onto the road. He also shared a Volkswagen Golf GTI with Denny Hulme in the 1979 Benson & Hedges 500 at Pukekohe Park Raceway in New Zealand.  In 1980 he made a comeback to regular competition, in the British Saloon Car Championship with the works-backed GTi Engineering Audi team. For the 1980 season Moss was the team's number two driver to team co-owner Richard Lloyd. For the 1981 season Moss stayed with Audi, as the team moved to Tom Walkinshaw Racing management, driving alongside Martin Brundle.  Throughout his retirement he raced in events for historic cars, driving on behalf of and at the invitation of others, as well as campaigning his own OSCA FS 372 and other vehicles.  On 9 June 2011 during qualifying for the Le Mans Legends race, Moss announced on Radio Le Mans that he had finally retired from racing, saying that he had scared himself that afternoon. He was 81.

Problem: Joy Division were an English post-punk band formed in 1976 in Salford, Greater Manchester. Originally named Warsaw, the band consisted of singer-songwriter Ian Curtis, guitarist and keyboardist Bernard Sumner, bass player Peter Hook and drummer Stephen Morris. The band was formed by Sumner and Hook after attending a 4 June 1976 Sex Pistols concert at the Lesser Free Trade Hall in Manchester. While Joy Division's early recordings were heavily influenced by early punk, they evolved a unique sound, aided by producer Martin Hannett, which earned their reputation as pioneers of the post-punk movement.

Joy Division's style quickly evolved from their punk roots. Their sound during their early inception as Warsaw was described as generic and "undistinguished punk-inflected hard-rock". Critic Simon Reynolds observed how the band's originality only "really became apparent as the songs got slower", and their music took on a "sparse" quality. According to Reynolds, "Hook's bass carried the melody, Bernard Sumner's guitar left gaps rather than filling up the group's sound with dense riffage and Steve Morris' drums seemed to circle the rim of a crater." According to music critic Jon Savage, "Joy Division were not punk but they were directly inspired by its energy". In 1994 Sumner said the band's characteristic sound "came out naturally: I'm more rhythm and chords, and Hooky was melody. He used to play high lead bass because I liked my guitar to sound distorted, and the amplifier I had would only work when it was at full volume. When Hooky played low, he couldn't hear himself. Steve has his own style which is different to other drummers. To me, a drummer in the band is the clock, but Steve wouldn't be the clock, because he's passive: he would follow the rhythm of the band, which gave us our own edge."  By Closer, Curtis had adapted a low baritone voice, drawing comparisons to Jim Morrison of the Doors (one of Curtis's favourite bands).  Sumner largely acted as the band's director, a role he continued in New Order. While Sumner was the group's primary guitarist, Curtis played the instrument on a few recorded songs and during a few shows. Curtis hated playing guitar, but the band insisted he do so. Sumner said, "He played in quite a bizarre way and that to us was interesting, because no one else would play like Ian". During the recording sessions for Closer, Sumner began using self-built synthesisers and Hook used a six-string bass for more melody.  Hannett "dedicated himself to capturing and intensifying Joy Division's eerie spatiality". Hannett believed punk rock was sonically conservative because of its refusal to use studio technology to create sonic space. The producer instead aimed to create a more expansive sound on the group's records. Hannett said, "[Joy Division] were a gift to a producer, because they didn't have a clue. They didn't argue". Hannett demanded clean and clear "sound separation" not only for individual instruments, but even for individual pieces of Morris's drumkit. Morris recalled, "Typically on tracks he considered to be potential singles, he'd get me to play each drum on its own to avoid any bleed-through of sound". Music journalist Richard Cook noted that Hannett's role was "crucial". There are "devices of distance" in his production and "the sound is an illusion of physicality".
