The Lucky Star is an English comic opera, in three acts, composed by Ivan Caryll, with dialogue by Charles H. Brookfield (revised by Helen Lenoir) and lyrics by Adrian Ross and Aubrey Hopwood. It was produced by the D'Oyly Carte Opera Company and opened at the Savoy Theatre on 7 January 1899 for a run of 143 performances.
The opera starred the usual Savoy Theatre cast from that period, including Walter Passmore, Henry Lytton, Robert Evett, Ruth Vincent, Emmie Owen and Isabel Jay. Direction was by Richard Barker, choreography was by Willie Warde, and costumes were designed by Percy Anderson.
The opera is based on L'étoile, written in 1877 by Eugène Leterrier and Albert Vanloo, with additional material by Paul Verlaine and music by Emmanuel Chabrier. It is also based on The Merry Monarch, an American translation of L'étoile by J. Cheever Goodwin with music by Woolson Morse, produced in 1890. Caryll used a small amount of Chabrier's music in the first act finale.
The Lucky Star was the only Savoy Opera where a woman plays a man's part. The piece has many other characteristics of Edwardian musical comedy, which had become popular on the London stage in the 1890s – broader comedy, a thin romance, bright tunes, comedians, a chorus of pretty girls, some risqué situations, a "coon" song, songs regarding news of the day, separate authors of dialogue and lyrics, and a star, Walter Passmore. This half-musical, half-comic opera, did not appeal strongly to the Savoy Theatre's audiences and was unable to achieve a long run.
