Princess Theatre, New York City in the context of "Sixth Avenue (Manhattan)"

Musical theatre is a form of theatrical performance that combines songs, spoken dialogue, acting and dance. The story and emotional content of a musical – humor, pathos, love, anger – are communicated through words, music, movement and technical aspects of the entertainment as an integrated whole. Although musical theatre overlaps with other theatrical forms like opera and dance, it may be distinguished by the equal importance given to the music as compared with the dialogue, movement and other elements. Since the early 20th century, musical theatre stage works have generally been called, simply, musicals.

Although music has been a part of dramatic presentations since ancient times, modern Western musical theatre emerged during the 19th century, with many structural elements established by the light opera works of Jacques Offenbach in France, Gilbert and Sullivan in Britain and the works of Harrigan and Hart in America. These were followed by Edwardian musical comedies, which emerged in Britain, and the musical theatre works of American creators like George M. Cohan at the turn of the 20th century. The Princess Theatre musicals (1915–1918) were artistic steps forward beyond the revues and other frothy entertainments of the early 20th century and led to such groundbreaking works as Show Boat (1927), Of Thee I Sing (1931) and Oklahoma! (1943). Some of the best-known musicals through the decades that followed includeMy Fair Lady (1956), The Fantasticks (1960), Hair (1967), A Chorus Line (1975), Les Misérables (1985), The Phantom of the Opera (1986), Rent (1996), Wicked (2003) and Hamilton (2015).

F. Ray Comstock (27 August 1878 – 15 October 1949) was an American theatrical producer and theater operator.He pioneered the intimate musical comedy, staging several successful comedies at his Princess Theatre in Manhattan.He also produced spectacular musicals, variety shows and serious plays by authors such as Henrik Ibsen and Maxim Gorky.

Guy Reginald Bolton (23 November 1884 – 4 September 1979) was an Anglo-American playwright and writer of musical comedies. Born in England and educated in France and the US, he trained as an architect but turned to writing. Bolton preferred working in collaboration with others, principally the English writers P. G. Wodehouse and Fred Thompson, with whom he wrote 21 and 14 shows respectively, and the American playwright George Middleton, with whom he wrote ten shows. Among his other collaborators in Britain were George Grossmith Jr., Ian Hay and Weston and Lee. In the US, he worked with George and Ira Gershwin, Kalmar and Ruby and Oscar Hammerstein II.

Bolton is best known for his early work on the Princess Theatre musicals during the First World War with Wodehouse and the composer Jerome Kern. These shows moved the American musical away from the traditions of European operetta to small scale, intimate productions with what the Oxford Encyclopedia of Popular Music calls "smart and witty integrated books and lyrics, considered to be a watershed in the evolution of the American musical." Among his 50 plays and musicals, most of which were considered "frothy confections", additional hits included Primrose (1924), the Gershwins' Lady, Be Good (1924) and especially Cole Porter's Anything Goes (1934).
