finished album. Duran Duran spent five to six weeks recording in Montserrat. Peter Wade-Schwier acted as engineer during these sessions. Tracks produced at AIR included "The Reflex" and "Union of the Snake" by mid-June 1983, as well as the chorus of "New Moon on Monday". Chic backing vocalists Michelle Cobbs and B. J. Nelson were flown in from New York City to provide backing vocals for "The Reflex". The group's time at AIR proved irritating due to encountering numerous technical problems. Keyboardist Nick Rhodes later said that the tape machines failed to run at the correct speeds. Little elaborated: "Anything that was in tune at the beginning was out of tune by the time we got to the end." When the producers complained to the local studio engineers about the faulty equipment, the engineers passed them off as whiny and unprofessional. With a deadline of a Christmas release, the band members were worried the album would not be delivered on time. Duran Duran also encountered personal conflicts at AIR. Their massive success led to rising tensions between the band members, primarily due to inflated egos and the presence of the members' girlfriends. Paul Berrow later said of the period: "At first it was military—videos, tour, album, tour—but what do you do when you get there? [You] get a girlfriend, and a demanding one almost certainly—and then the whole entity changes. The band comes together for just work and then goes away again to a new set of friends. There's conflict among the merry men." Recording faced a minor setback when Rhodes, suffering from exhaustion, stress and sun burning, collapsed one night and had to be airlifted to a hospital in Miami, Florida. Newspapers reported it was due to an episode of paroxysmal tachycardia, or an abnormally fast heartbeat. After the incident, the keyboardist started taking his health much more seriously, laying off drugs and limiting himself to red wine. On 20 July 1983, Duran Duran briefly halted the sessions to play at the Prince's Trust concert with Dire Straits at the Dominion Theatre in London, with Prince Charles and Princess Diana in attendance. Having not performed live in several months, Duran Duran were under-rehearsed, leading to a poor performance amidst technical problems, but spoke briefly with the royal couple afterwards. A photograph taken of Diana with singer Simon Le Bon, John and Andy made headlines the following day. Three days
