James Douglas Muir "Jay" Leno /ˈlɛnoʊ/ (born April 28, 1950) is an American stand-up comedian and television host.

From 1992 to 2009, Leno was the host of NBC's The Tonight Show with Jay Leno. Beginning in September 2009, Leno started a primetime talk show, titled The Jay Leno Show, which aired weeknights at 10:00 p.m. (Eastern Time, UTC-5), also on NBC. After The Jay Leno Show was canceled in January 2010 amid a host controversy, Leno returned to host The Tonight Show with Jay Leno on March 1, 2010.

James "Jay" Leno was born in New Rochelle, New York, in 1950. His mother, Catherine (née Muir; 1911–1993), a homemaker, was born in Greenock, Scotland, and came to the United States at age 11. Leno's father, Angelo (1910–1994), who worked as an insurance salesman, was born in New York to immigrants from Flumeri, Italy. Leno grew up in Andover, Massachusetts, and although his high school guidance counselor recommended that he drop out of school, he later obtained a Bachelor's degree in speech therapy from Emerson College, where he started a comedy club in 1973. Leno's siblings include his late older brother, Patrick, who was a Vietnam veteran and a lawyer.

Igor Fyodorovich Stravinsky (sometimes spelled Strawinsky or Stravinskii; Russian: Игорь Фёдорович Стравинский, transliterated: Igorʹ Fëdorovič Stravinskij; Russian pronunciation: [ˌiɡərʲ ˌfʲjodɐrɐvʲɪtɕ strɐˈvʲinskʲɪj]; 17 June [O.S. 5 June] 1882 – 6 April 1971) was a Russian, and later French and American composer, pianist and conductor. He is acknowledged by many as one of the most important and influential composers of the 20th century.

Stravinsky's compositional career was notable for its stylistic diversity. He first achieved international fame with three ballets commissioned by the impresario Sergei Diaghilev and first performed in Paris by Diaghilev's Ballets Russes: The Firebird (1910), Petrushka (1911) and The Rite of Spring (1913). The Rite of Spring, which provoked a riot during its premiere, transformed the way in which subsequent composers thought about rhythmic structure and was largely responsible for Stravinsky's enduring reputation as a musical revolutionary who pushed the boundaries of musical design. His so-called Russian phase was followed in the 1920s by a period in which he turned to neoclassical music. The works from this period tended to make use of traditional musical forms (concerto grosso, fugue and symphony). They frequently concealed a vein of intense emotion beneath a surface appearance of detachment or austerity and often paid tribute to the music of earlier masters, for example J.S. Bach and Tchaikovsky. In the 1950s, Stravinsky adopted serial procedures. His compositions of this period shared traits with examples of his earlier output: rhythmic energy, the construction of extended melodic ideas out of a few two- or three-note cells and clarity of form, of instrumentation and of utterance.
