Miss Saigon composer Claude Michel Schonberg and producer Cameron Mackintosh spoke as the 1991 musical finished its final performance at the Broadway Theatre Jan. 28. The Sunday matinee marked Miss Saigon's 4,097th performance. The musical is inspired by the same novel that prompted the David Belasco play and the Puccini opera, Madama Butterfly: a novel called "Madame Chrysanthemum." Miss Saigon's action is largely set during the 1975 fall of Saigon, when American troops pulled out of Vietnam. With the Broadway production shuttered, the Schonberg-Alain Boublil-Richard Maltby Jr. show will see a smattering of regional productions, including TX's Theatre Under the Stars' production, set to run March 20-April 1.
