Trevor Nunn directed the hauntingly spare revival of A Little Night Music, which originated at London's Menier Chocolate Factory last year prior to arriving on Broadway Nov. 24, 2009. Night Music officially opened Dec. 13 at the Walter Kerr.

A Little Night Music, according to the producers, "is set in a weekend country house in turn of the century Sweden, bringing together surprising liaisons, long simmering passions and a taste of love's endless possibilities. Hailed as witty and wildly romantic, the story centers on the elegant actress Desirée Armfeldt and the spider's web of sensuality, intrigue and desire that surrounds her." The creative team includes Lynne Page (choreography), Caroline Humphris (musical supervision), David Farley (set and costume design), Hartley T A Kemp (lighting design), Dan Moses Shreier and Gareth Owen (sound design), Paul Huntley (wig design), Jason Carr (orchestrations) and Rob Bowman (musical direction).

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."
