Information: - Vaudeville is a theatrical genre of variety entertainment. It was especially popular in the United States and Canada from the early 1880s until the early 1930s. A typical vaudeville performance is made up of a series of separate, unrelated acts grouped together on a common bill. Types of acts have included popular and classical musicians, singers, dancers, comedians, trained animals, magicians, strongmen, female and male impersonators, acrobats, illustrated songs, jugglers, one-act plays or scenes from plays, athletes, lecturing celebrities, minstrels, and movies. A vaudeville performer is often referred to as a "vaudevillian". - Entertainment is a form of activity that holds the attention and interest of an audience, or gives pleasure and delight. It can be an idea or a task, but is more likely to be one of the activities or events that have developed over thousands of years specifically for the purpose of keeping an audience's attention. Although people's attention is held by different things, because individuals have different preferences in entertainment, most forms are recognisable and familiar. Storytelling, music, drama, dance, and different kinds of performance exist in all cultures, were supported in royal courts, developed into sophisticated forms and over time became available to all citizens. The process has been accelerated in modern times by an entertainment industry that records and sells entertainment products. Entertainment evolves and can be adapted to suit any scale, ranging from an individual who chooses a private entertainment from a now enormous array of pre-recorded products; to a banquet adapted for two; to any size or type of party, with appropriate music and dance; to performances intended for thousands; and even for a global audience. - The Cox Twins , Frank and Fred , ( born 4 December 1920 in Cardiff , Wales ) , were British entertainers in the Music Hall tradition .

It involved a mixture of popular songs, comedy, speciality acts, and variety entertainment. The term is derived from a type of theatre or venue in which such entertainment took place. British music hall was similar to American vaudeville, featuring rousing songs and comic acts, while in the United Kingdom the term "vaudeville"' referred to more working-class types of entertainment that would have been termed "burlesque" in America. - The Victorian era was the period of Queen Victoria's reign, from 20 June 1837 until her death on 22 January 1901. It was a long period of peace, prosperity, "refined sensibilities" and national self-confidence for the United Kingdom. Some scholars date the beginning of the period in terms of sensibilities and political concerns to the passage of the Reform Act 1832. What is the relationship between 'the cox twins' and 'male'?
