George Robey

Context: By 1890 Robey had become homesick, and so he returned to South London, where he took employment in a civil engineering company. He also joined a local branch of the Thirteen Club, whose members, many of whom were amateur musicians, performed in small venues across London. Hearing of his talent, the founder of the club, W. H. Branch, invited Robey to appear at Anderton's Hotel in Fleet Street, where he performed the popular new comic song "Where Did You Get That Hat?". Robey's performance secured him a number of private engagements for which he was paid a guinea a night. By the early months of 1891, Robey was much in demand, and he decided to change his stage name. He swapped "Wade" for "Robey" after working for a company in Birmingham that bore the latter name. It was at around this time that he met E. W. Rogers, an established music hall composer who wrote songs for Marie Lloyd and Jenny Hill. For Robey, Rogers wrote three songs: "My Hat's a Brown 'Un", "The Simple Pimple" and "It Suddenly Dawned Upon Me". In 1891 Robey visited the Royal Aquarium in Westminster where he watched "Professor Kennedy", a burlesque mesmerist from America. After the performance, Robey visited Kennedy in his dressing room and offered himself as the stooge for his next appearance. They agreed that Robey, as his young apprentice, would be "mesmerised" into singing a comic song. At a later rehearsal, Robey negotiated a deal to sing one of the comic songs that had been written for him by Rogers. Robey's turn was a great success, and as a result he secured a permanent theatrical residency at the venue. Later that year, he appeared as a solo act at the Oxford Music Hall, where he performed "The Simple Pimple" and "He'll Get It Where He's Gone to Now". The theatrical press soon became aware of his act, and The Stage called him a "comedian with a pretty sense of humour [who] delivers his songs with considerable point and meets with all success". In early 1892, together with his performances at the Royal Aquarium and the Oxford Music Hall, Robey starred alongside Jenny Hill, Bessie Bonehill and Harriet Vernon at the Paragon Theatre of Varieties in Mile End, where, according to his biographer Peter Cotes, he "stole the notices from experienced troupers". That summer, Robey conducted a music hall tour of the English provinces which began in Chatham and took him to Liverpool, at a venue owned by the mother of the influential London impresario Oswald Stoll. Through this engagement Robey met Stoll, and the two became lifelong friends. In early December, Robey appeared in five music halls a night, including Gatti's Under the Arches, the Tivoli Music Hall and the London Pavilion. In mid-December, he travelled to Brighton, where he appeared in his first Christmas pantomime, Whittington Up-to-Date. Pantomime would become a lucrative and regular source of employment for the comedian. Cotes calls Robey's festive performances the "cornerstone of his comic art", and the source of "some of his greatest successes". CANNOTANSWER
