Featuring an international cast of artists Miss Saigon is a musical by Claude-Michel Schonberg and Alain Boublil, with lyrics by Boublil and Richard Maltby, Jr.. It is based on Giacomo Puccini's opera MADAME BUTTERFLY, and similarly tells the tragic tale of a doomed romance involving an Asian woman abandoned by her American lover. The setting of the plot is relocated to 1970s Saigon during the Vietnam War, and Madame Butterfly's story of marriage between an American lieutenant and Japanese girl is replaced by a romance between an American GI and a Vietnamese bar girl. The musical premiered at the Theatre Royal, Drury Lane, in London on 20 September 1989, closing after over four thousand performances, on 30 October 1999. It opened on Broadway at the Broadway Theatre in 1991 and subsequently played in many other cities and embarked on tours. The musical represented Schonberg and Boublil's second major success, following LES MISERABLES in 1985. As of December 2012, Miss Saigon is still the eleventh longest-running Broadway musical in musical theatre history.
