Sally is a musical comedy with music by Jerome Kern, lyrics by Clifford Grey and book by Guy Bolton (inspired by the 19th century show, Sally in our Alley), with additional lyrics by Buddy De Sylva, Anne Caldwell and P. G. Wodehouse. The plot hinges on a mistaken identity: Sally, a waif, is a dishwasher at the Alley Inn. She poses as a famous foreign ballerina and rises to fame (and finds love) through joining the Ziegfeld Follies. There is a rags to riches story, a ballet as a centrepiece, and a wedding as a finale. "Look for the Silver Lining" continues to be one of Kern's most familiar songs. The song is lampooned by another song, "Look for a Sky of Blue," in Rick Besoyan's satirical 1959 musical Little Mary Sunshine. The piece was first produced in 1920 on Broadway by Florenz Ziegfeld, and ran for 570 performances, one of the longest runs on Broadway up to that time. The show was designed as a debut star vehicle for Marilyn Miller. It had a successful London run and was revived several times on Broadway and in the West End, although it has had few productions since the 1950s. The musical was adapted into a 1925 silent film and a 1929 musical film. Background and original production Kern, Bolton, and Wodehouse had collaborated on a number of musical comedies at the Princess Theatre. The story combined the innocence of these earlier "Princess musicals" with the lavishness of the "Ziegfeld Follies" formula. The score recycles some material from previous Kern shows, including "Look for the Silver Lining" and "Whip-poor-will" (with lyrics by De Sylva, from the flop "Zip Goes a Million"); "The Lorelei" (lyrics by Anne Caldwell); and "You Can't Keep a Good Girl Down" and "The Church 'Round the Corner" (lyrics by Wodehouse). Grey supplied the lyrics for the few new songs in the score. At the request of Ziegfeld, Victor Herbert was engaged to write the music to "The Butterfly Ballet" in Act Three. The musical was originally produced by Florenz Ziegfeld, opening on December 21, 1920 at the New Amsterdam Theatre on Broadway. It ran for 570 performances, which was one of the longest runs on Broadway up to that time. By the time it closed in 1924 (including revivals), it would prove to be among the top five money makers of the 1920s. The show was designed
