Directly after the 1962 awards ceremony, Corbett does his impersonation of Harold Wilson with reference to his White Heat of Technology speech. Wilson did not become Prime Minister for another two years and the White Heat speech was even later. However, the writer made this 'error' quite deliberately. He took dramatic license. Dates were fudged throughout the piece, so though the award ceremony was in fact held in 1962, the film avoids placing it in time. Harry's party trick was his Harold Wilson impression; that was the most appropriate moment in the piece to give him the chance to do his thing.
