Penny gaff

A penny gaff was a popular entertainment for the lower classes in 19th-century England. It consisted of short, theatrical entertainments which could be staged wherever space permitted, such as the back room of a public house or small hall. Unsophisticated, the props and scenery rarely consisted of more than a stage and a piano. The lessee of the venue would often stand by the stage, calling out when each act should finish in an attempt to maximise the evening's revenue.
