Billy the Kid is a 1938 ballet written by the American composer Aaron Copland on commission from Lincoln Kirstein.
 It was choreographed by Eugene Loring for Ballet Caravan.
 Along with "Rodeo" and "Appalachian Spring", it is one of Copland's most popular and widely performed pieces.
 The ballet is most famous for its incorporation of several cowboy tunes and American folk songs and, although built around the figure and the exploits of Billy the Kid, is not so much a biography of a notorious but peculiarly appealing desperado as it is a perception of the pioneer West, in which a figure such as Billy played a vivid role.

 Picasso also drew a sketch with pen on paper of "La Boutique fantasque" ("La course"), (1919, choreography: Massine).

Aschenbrödel ("Cinderella") is a ballet written by Johann Strauss II.

Jane Avril (9 June 186817 January 1943) was a French can-can dancer made famous by Henri de Toulouse-Lautrec through his paintings.
 Extremely thin, 'given to jerky movements and sudden contortions', she was nicknamed "La Mélinite", after an explosive.
Leonid Fyodorovich Myasin (Russian: Леони́д Фёдорович Мя́син ), better known in the West by the French transliteration as Léonide Massine (9 August [O.S. 28 July] 1896 15 March 1979), was a Russian choreographer and ballet dancer.
 Massine created the world's first symphonic ballet, "Les Présages", and many others in the same vein.
 Besides his "symphonic ballets," Massine choreographed many other popular works during his long career, some of which were serious and dramatic, and others lighthearted and romantic.
 He created some of his most famous roles in his own comic works, among them the Can-Can Dancer in "La Boutique fantasque" (1919), the Hussar in "Le Beau Danube" (1924), and, perhaps best known of all, the Peruvian in "Gaîté Parisienne" (1938).
