In a 1987 interview with Option, Morris said that they "just thought the songs were sort of sympathetic and more uplifting than depressing. But everyone's got their own opinion." Deborah Curtis recalled that only with the release of Closer did many who were close to the singer realise "[h]is intentions and feelings were all there within the lyrics". The surviving members regret not seeing the warning signs in Curtis's lyrics. Morris said that "it was only after Ian died that we sat down and listened to the...
