The "Tonight Quintet" is a number from the musical West Side Story (1957), with music by Leonard Bernstein and lyrics by Stephen Sondheim. Carol J. Oja has written that, "with the 'Tonight' quintet, Bernstein once again created a masterpiece of ensemble, one that rivals the best of such moments in European opera." Her remark echoes the earlier view of Will Crutchfield. In his review of the 1984 studio performance of West Side Story, which was conducted by Bernstein himself, Crutchfield wrote that the release of the recording "is above all an occasion for celebrating one of the great operas of our century. ... This idea is hotly resisted, but the best argument for it is here on the records in the music itself. I can see no reason why the 'Tonight' ensemble should not be compared to the quartet from Rigoletto."
Based on the duet between Maria and Tony earlier in the musical, "Tonight", the five parts of the quintet are sung by the Jets, the Sharks, Tony, Maria, and Anita. The song begins with the parts sung in turn, and then overlapping and building to the final line, "Tonight," sung by the ensemble with multiple harmonies. The Jets and the Sharks are rival gangs anticipating the "rumble" which will settle a territorial feud that has been brewing between them for some time now. Both groups are confident that the fight will end in their favor. The song is used to show anticipation to the coming night, which will end up being the climactic part of the play.
Anita sings of her anticipation for her boyfriend, Bernardo, the leader of the Sharks, to return after the rumble. She knows that he is usually riled up after a fight like this and she looks forward to having some intimate time together and "getting her kicks." In the 1961 film version of West Side Story, Anita sings "He'll walk in hot and tired, poor dear / No matter if he's tired, as long as he's here" rather than "He'll walk in hot and tired, so what / No matter if he's tired, as long as he's hot."
Tony, a member of the Jets, has fallen in love with Maria, Bernardo's sister. At Maria's request, he plans to go to the rumble and stop the fight. Maria and Tony sing about their eagerness to see each other after Tony returns; they believe that after Tony stops the fight, the tension surrounding their forbidden love will finally vanish and the night will be "endless." They are frustrated by the seemingly slow place of the present day while they are anticipating the coming night. The dramatically contrasting elements in this scene and their corresponding presentation in music have been compared to the trio "Cosa sento!" from Mozart's The Marriage of Figaro.
Part of the song was parodied in a promo to the 2005 WWE Royal Rumble event where the Superstars from Raw and Smackdown gather for a rumble until Vince McMahon wakes up from the dream sequence and says that's not the rumble he had in mind.

Of all the Bernstein shows, this one achieved the most deeply integrated fusion of otherwise disparate musical worlds. "Dance at the Gym" spins through popular Latin genres and gestures. "Cool" conjures up the post-bop world of jazz pianists Lennie Tristano or Dave Brubeck. "One Hand, One Heart" uncannily unites a hymn with a pop song, set to the meter of a waltz. "Gee, Officer Krupke" draws on the comedic agitprop of Marc Blitzstein. And with the "Tonight" quintet, Bernstein once again created a masterpiece of ensemble, one that rivals the best of such moments in European opera.The co-editor, Burton Bernstein, is the brother of Leonard Bernstein; see Ireland, Corydon (October 19, 2006).
