Guy Reginald Bolton 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.

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.
