In 1931, Reader, a Rover Scout trying to make his mark in theatre in the USA and London, was asked to write a Scout-based variety show to raise money for a swimming pool at Downe Scout Camp (now a Scout Association National Activity Centre). Rehearsals began under Reader's direction on 25 May 1932, his 29th birthday).[1]
Initially the show did not have a title, but during a rehearsal break, Reader recalled, he asked a cast member if everyone was ready, to which the response was "Aye, aye Skip, the gang's all here". The first production, The Gang's All Here, ran between 30 October and 1 November 1932 at the Scala Theatre in central London.[1]
