"Send In the Clowns" is a song written by Stephen Sondheim for the 1973 musical A Little Night Music, an adaptation of Ingmar Bergman's 1955 film Smiles of a Summer Night. It is a ballad from Act Two, in which the character Desirée reflects on the ironies and disappointments of her life. Among other things, she looks back on an affair years earlier with the lawyer Fredrik, who was deeply in love with her, but whose marriage proposals she had rejected. Meeting him after so long, she realizes she is in love with him and finally ready to marry him, but now it is he who rejects her: He is in an unconsummated marriage with a much younger woman. Desirée proposes marriage to rescue him from this situation, but he declines, citing his dedication to his bride. Reacting to his rejection, Desirée sings this song. The song is later reprised as a coda after Fredrik's young wife runs away with his son, and Fredrik is finally free to accept Desirée's offer.[1]
Sondheim wrote the song specifically for Glynis Johns, who originated the role of Desirée on Broadway. The song is structured with four verses and a bridge, and uses a complex compound meter. It became Sondheim's most popular song after Frank Sinatra recorded it in 1973 and Judy Collins's version charted in 1975 and 1977. Subsequently, numerous other artists recorded the song, and it has become a standard.
