The first colour edition of Blue Peter aired on 14 September 1970, and the last black and white edition on 24 June 1974. A regular feature of the 1970s were the Special Assignments, which were essentially reports on interesting topics, filmed on location. Singleton took this role, and in effect became the programme's roving reporter. Blue Peter also offered breaking news on occasion, such as the 1971 eruption of Mount Etna, as well as unique items such as the first appearance of Uri Geller on British television. In May 1976, presenter Lesley Judd interviewed Otto Frank, father of Anne Frank, after he had agreed to bring his daughter's diaries to Britain. From 1971, the summer expedition from the previous year was edited into special programmes broadcast under the title Blue Peter Flies The World, televised during the summer break when the team were recording the latest expedition. The first was shown in July 1971 and featured the expedition to Jamaica
