The genre commonly referred to as the ‘concert party’ remains largely neglected by scholars of popular entertainment. In this article Bernard Ince presents a new reading of this most distinctive and underrated branch of theatrical activity. The period before the First World War saw the growth of an ‘industry’ which provided seaside amusement during the summer months. During the inter-war years, however, a more sophisticated form developed whose performative characteristics drew increasingly on revue and cabaret. The period after the Second World War saw further adaptations that gave rise to the summer show, an altogether more lavish spectacle that nonetheless inherited much of the concert party ethos of earlier times. Changes in audience expectations and public holiday preferences, the catastrophe of the two world wars, and the emergence of radio and film were challenges all successfully negotiated, further underscoring the resilience and adaptability of the genre. In the wider context, the concert party not only offered a critical path to the variety stage but in the simplicity of basic form also provided a template for experimentation and innovation.
