<P0-S0> John Clifford, born June 12th is the founder / artistic director of the original Los Angeles Ballet (1974–1985), and the chamber sized touring ensemble, Ballet of Los Angeles (1988–1991) and the creator of “CASABLANCA, THE DANCE” produced by Warner Bros. <P0-S1>  Theatre Ventures, Inc. (which premiered in Beijing, China at the historic "Great Hall of the People" in 2005) and his Los Angeles Dance Theater. <P0-S2>  Before that time,Clifford was a principal dancer and choreographer with George Balanchine’s New York City Ballet, (1966–1974) and guest artist from 1974–1980, and was widely considered to be Balanchine’s protégé (Saturday Review). <P0-S3>  He choreographed his first (of 8) ballets for the NYC Ballet under Balanchine at age 20 thus making him the 2nd youngest choreographer in history ever to be attached to a major company. <P0-S4>  The first was Balanchine himself who was 20 yrs-old when he choreographed his first ballet for Serge Diaghilev's "Ballets Russes." <P0-S5>  During his time with Balanchine, in his early 20's, he also was a guest choreographer with co's ranging from the San Francisco Ballet, to the Royal Winnipeg Ballet, to the Deutsche Oper Ballet in Berlin. <P0-S6>  Clifford's works were also featured in many TV shows and movies, such as "Flashdance," "The Man Who Loved Women," and TV series such as "Dynasty," "Glitter," and other shows produced by Blake Edwards and Aaron Spelling. <SEP> <P1-S0> The 1917 Petipa/Ivanov/Drigo revival of Swan Lake is a famous version of the ballet "Swan Lake", (ru. " <P1-S1> Лебединое Озеро"), (fr. <P1-S2>  "Le Lac des Cygnes"). <P1-S3>  This is a ballet by Pyotr Ilyich Tchaikovsky based on an ancient German legend, presented in either four acts, four scenes (primarily outside Russia and Eastern Europe), three acts, four scenes (primarily in Russia and Eastern Europe) or, more rarely, in two acts, four scenes. <P1-S4>  Originally choreographed by Julius Reisinger to the music of Pyotr Ilyich Tchaikovsky (opus 20), it was first presented as "The Lake of the Swans" by the Ballet of the Moscow Imperial Bolshoi Theatre on 20 February/4 March 1877 (Julian/Gregorian calendar dates) in Moscow, Russia. <P1-S5>  Although the ballet is presented in many different versions, most ballet companies today base their stagings both choreographically and musically on this revival by Marius Petipa and Lev Ivanov, staged for the Imperial Ballet, first presented on 15 January/27 January 1895, at the Imperial Mariinsky Theatre in St. Petersburg, Russia instead of the original version. <SEP> <P2-S0> Gil Boggs is the Artistic Director of Colorado Ballet in Denver, Colorado. <P2-S1>  Boggs accepted the position of Artistic Director with Colorado Ballet in the Spring of 2006. <P2-S2>  In August 2014, Boggs re-signed a five-year contract to remain as Colorado Ballet's Artistic Director. <P2-S3>  During Boggs’ tenure with Colorado Ballet, he has re-staged full-length productions of Swan Lake, The Sleeping Beauty, Giselle, Don Quixote and Coppélia along with adding new full-length productions of Romeo & Juliet, Cinderella, Le Corsaire, Beauty and the Beast and Peter Pan. <P2-S4>  Boggs has also presented 15 world premieres and 12 Colorado Ballet premieres by choreographers Twyla Tharp, Lar Lubovitch, Antony Tudor, Val Caniparoli, Dwight Rhoden and Lynne Taylor-Corbett. <SEP> <P3-S0>  The music was composed by Pyotr Ilyich Tchaikovsky (his opus 66). <P3-S1> The Sleeping Beauty (Russian: Спящая красавица / "Spyashchaya krasavitsa") is a ballet in a prologue and three acts, first performed in 1890. <P3-S2>  The score was completed in 1889, and is the second of his three ballets. <P3-S3>  The original scenario was conceived by Ivan Vsevolozhsky, and is based on Charles Perrault's "La Belle au bois dormant". <P3-S4>  The choreographer of the original production was Marius Petipa.
