Document 15: Tonight Quintet: The "Tonight Quintet" is a song 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"."
