The Imaginary Invalid
The Mercury is best known for its production of "The Imaginary Invalid" starring Finch on the floor of O'Brien's Glass Factory in Sydney in 1948; this was seen by Laurence Olivier and Vivien Leigh who were so impressed they invited Finch to come to London. Kay revived the company in 1952, and it ran for the next two years from a base at St James' Hall in Sydney. Among those who acted in Mercury shows over the years included Rod Taylor, Ruth Cracknell and Lloyd Berrell.
