 Singer took the lead in finding international funding for very ambitious co-productions, leading to the so-called 'Science Spectaculars' written by Nigel Calder, and then the 13-part "personal view" series such as "Civilisation" (1969) and "The Ascent of Man" (1973).He was also largely responsible for the historic 1967 "Our World" global satellite broadcast, which featured The Beatles.Singer was the controller of BBC2 from 1974 until 1978, who replaced Robin Scott and was replaced himself by Brian Wenham.
