Miss Saigon is a West End musical by Claude-Michel Schönberg 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 American Lieutenant and Japanese geisha coupling is replaced by a romance between an American GI and a Vietnamese bar girl.
The musical represented Schönberg and Boublil's second major success, following Les Misérables in 1980. As of August 2010, Miss Saigon is still the 10th longest-running Broadway musical in musical theatre history.
