A Little Night Music, according to press notes, "follows three lovestruck couples as they lose – and find – each other during a long midsummer night on a country estate."
A Little Night Music — featuring a score by Sondheim and a book by Wheeler — originally opened at Broadway's Shubert Theatre on Feb. 25, 1973, with a cast that included Glynis Johns as Desiree, Len Cariou as Fredrik and Hermione Gingold as Madame Armfeldt. The show, directed by Harold Prince, garnered five 1973 Tony Awards, including one for Best Musical. The Sondheim score features the composer's best-known tune, "Send in the Clowns," as well as "Every Day a Little Death," "The Miller's Son" and "A Weekend in the Country." Proceeds will benefit the not-for-profit Roundabout Theatre Company.
