A Trip to Chinatown is a musical comedy in three acts with a book by Charles H. Hoyt, music by Percy Gaunt and lyrics by Hoyt. In addition to the Gaunt and Hoyt score, many songs were interpolated into the score at one time or another during the run, as was fashionable for musicals of the era. The story concerns a widow who accidentally maneuvers several young suburban couples into a big city restaurant and brings romance to them and herself, as in Hello, Dolly!

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.
