John McMaster was" The first real Clear", according to Hubbard himself and also narrated the "Orientation" video. McMaster was sent by LRH on a world tour to promote the 1960's Scientology 'Total Freedom' campaign of standard technology. John undertook very public visits to America, Australia and New Zealand and was instrumental to a resurgence of public interest in Scientology books and courses. He was eventually interviewed in length by ABC television in 1968 where he carried of some excellent PR work. Hubbard soon became disillusioned with McMaster and demoted him. McMaster eventually had enough abuse and left the organisation for the rest of his long life. John had family in Australia from a previous marriage and in later years confirmed that he was a homosexual male. He often referred to his former friend Hubbard as "Fatty"in later years over the perceived betrayal. McMaster was one of the most respected and skilled Class VII Auditors and an able Case Supervisor who helped many people.
