IN: Vaslav Nijinsky (also Vatslav; Russian: Vatslav Fomich Nizhinskii; Russian: ['vatsl@f f@'mjitc njI'zinskjIj]; Polish: Waclaw Nizynski; 12 March 1889/1890 - 8 April 1950) was a ballet dancer and choreographer cited as the greatest male dancer of the early 20th century.

Nijinsky spent his summer after graduation rehearsing and then performing at Krasnoe Selo in a makeshift theatre with an audience mainly of army officers. These performances frequently included members of the Imperial family and other nobility, whose support and interest were essential to a career. Each dancer who performed before the Tsar received a gold watch inscribed with the Imperial Eagle. Buoyed by Nijinsky's salary, his new earnings from giving dance classes, and his sister Bronia's employment with the ballet company, the family moved to a larger flat on Torgovaya Ulitsa. The new season at the Mariinsky theatre began in September 1907, with Nijinsky employed as coryphee on a salary of 780 roubles per year.  He appeared with Sedova, Lydia Kyasht and Karsavina. Kchessinska partnered him in La Fille Mal Gardee, where he succeeded in an atypical role for him involving humour and flirtation. Designer Alexandre Benois proposed a ballet based upon Le Pavillon d'Armide, choreographed by Fokine to music by Nikolai Tcherepnin. Nijinsky had a minor role, but it allowed him to show off his technical abilities with leaps and pirouettes. The partnership of Fokine, Benois and Nijinsky was repeated throughout his career. Shortly after, he upstaged his own performance, appearing in the Bluebird pas de deux from the Sleeping Beauty, partnering Lydia Kyasht. The Mariinsky audience was deeply familiar with the piece, but exploded with enthusiasm for his performance and his appearing to fly, an effect he continued to have on audiences with the piece during his career.  In subsequent years, Nijinsky was given several soloist roles. In 1910, Mathilde Kschessinska selected Nijinsky to dance in a revival of Petipa's Le Talisman. Nijinsky created a sensation in the role of the Wind God Vayou.
QUESTION: why were they essential?
IN: Elkie Brooks (born Elaine Bookbinder, 25 February 1945) is an English singer, a vocalist with the bands Dada and Vinegar Joe, and later a solo artist. She gained her biggest success in the late 1970s and 1980s and has been nominated twice for Brit Awards. She is known for her powerful husky voice and hit singles such as "Pearl's a Singer", "Lilac Wine", "Don't Cry Out Loud", "Fool (If You Think It's Over)", and "No More the Fool", and top-selling album Pearls.

Brooks was born Elaine Bookbinder in Broughton, Salford, the daughter of Marjorie Violet "Vi" (nee Newton) and Kalmon Charles "Charlie" Bookbinder. She was raised in Prestwich. She attended North Salford Secondary Modern School.  Her older brother is Anthony Bookbinder (born 28 May 1943), who went by the stage name of Tony Mansfield, and was drummer for Billy J. Kramer with the Dakotas, on their run of 1960s hit records.  According to Brooks, her unofficial debut was a gig at a club called the "Laronde" on Cheetham Hill Road, Manchester, when she was 13 years old. She first sang professionally at the age of 15, and her first record, a cover of Etta James's "Something's Got a Hold on Me", was released on Decca in 1964. Brooks spent most of the 1960s on Britain's cabaret scene, a period of her life that she did not particularly enjoy. In the mid 1960s she supported the Beatles in their Christmas show in London, then, as an established act, helped the Small Faces in their early career by introducing them at several venues. She went on to tour the United States with several bands, including the Animals.  After she met Pete Gage, whom she would marry, she joined the short-lived fusioneers Dada before forming Vinegar Joe with Gage and Robert Palmer. Brooks gained the reputation as the wild woman of rock 'n' roll due to her wild stage performances. After three albums, they split up in 1974, and Brooks and Palmer pursued separate solo careers. After a time as backing singer with the American southern boogie band Wet Willie, she returned to England.
