They are the final stars of Miss Saigon. Will Chase played the G.I. Chris in the musical's final Broadway performance Jan. 28. Joining him was Saigon original Tony Award-winning star, Lea Salonga, for whom the role of the self-sacrificing Vietnamese girl Kim became a signature role. 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 Claude Michel 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.
