Task: Question Answering
Input (English): Passage: Matlock was replaced by Rotten's friend and self-appointed "ultimate Sex Pistols fan" Sid Vicious. Born John Simon Ritchie, later known as John Beverley, Vicious was previously drummer of two inner circle punk bands, Siouxsie and the Banshees and The Flowers of Romance. He was also credited with introducing the pogo dance to the scene at the 100 Club. John Robb claims it was at the first Sex Pistols residency gig, 11 May 1976; Matlock is convinced it happened during the second night of the 100 Club Punk Special in September, when the Pistols were off playing in Wales. In Matlock's description, Rotten wanted Vicious in the band because "[i]nstead of him against Steve and Paul, it would become him and Sid against Steve and Paul. He always thought of it in terms of opposing camps".Julien Temple, then a film student whom McLaren had put on the Sex Pistols payroll to create a comprehensive audiovisual record of the band, concurs: "Sid was John's protégé in the group, really. The other two just thought he was crazy." McLaren later stated that, much earlier in the band's career, Vivienne Westwood had told him he should "get the guy called John who came to the store a couple of times" to be the singer. When Johnny Rotten was recruited for the band, Westwood said McLaren had got it wrong: "he had got the wrong John." It was John Beverley, the future Vicious, she had been recommending. McLaren approved the belated inclusion of Vicious, who had virtually no experience on his new instrument, on account of his look and reputation in the punk scene. 
Question: What was the full name of the person that introduced the pogo dance?
