The idea of an ex-CUOC club started in the heads of its first distinguished members: Paul Curzon, Colin Smith, and Tim Wiegand. Also involved were Jon Forster and Phil Slingsby who were still undergraduates at the time.
Paul Curzon had joined CUOC while he was doing his Ph.D. (1986-90) and even after that time, when he was a research assistant, he and his mates were "still all hanging around doing post-grad things, or being on the CUOC committee, pretending to still be students."
