he no longer had to impersonate a white minstrel on stage. He toured through New England with the Georgia Champion Minstrels in 1844. The bill called him "The Wonder of the World Juba, Acknowledged to be the Greatest Dancer in the World. Having danced with John Diamond at the Chatham Theatre for $500, and at the Bowery Theatre for the same amount, and established himself as the King of All Dancers. No conception can be formed of the variety of beautiful and intricate steps exhibited by him with ease. You must see to believe." In 1845, Juba began touring with the Ethiopian Minstrels. The troupe gave him top billing over its four white members, unprecedented for a black performer. From 1846, Juba toured with White's Serenaders, under the tutelage of Charles "Charlie" White, as a dancer and tambourine player off and on until at least 1850. He played a character named Ikey Vanjacklen, "the barber's boy" in a piece called "Going for the Cup, or, Old Mrs. Williams's Dance", one of the earliest known minstrel sketches. It focused on Juba's dancing in a milieu of competition and showing off. The plot follows two characters trying to fix a dance contest by soaping the floor in a way that will make all of the competitors fall except Ikey. They bet on Vanjacklen, but in the end, the judge steals the money. England tour, 1848 In 1848, a dancer billed as "Boz's Juba" performed in London, England. He was a member of the Ethiopian Serenaders, a blackface minstrel troupe under the leadership of Gilbert W. Pell (or Pelham). The company had performed in England two years prior, when they had made minstrelsy palatable to middle-class British audiences by adopting refinements such as formal wear. With Boz's Juba as its newest member, the company toured middle-class theaters and lecture halls in the British Isles for the next 18 months. The identity of Boz's Juba is open to doubt. "Boz" was a pen name used by Dickens. The Ethiopian Serenaders quoted from Dickens's American Notes in their press releases, and The Illustrated London News considered the black dancer to be the same person Dickens had seen in New York in 1842. Dickens never refuted the claims. Nevertheless, the Serenaders' assertions were promotional, and Dickens may not have remembered the exact look or characteristics of the dancer he had seen in the Five Points. Writers
