Ms. Blaine is most noted for having portrayed Miss Adelaide, the long-suffering, perpetually engaged chorus girl, in the Broadway and film versions of Guys and Dolls (1955). She originated the role in 1950 on Broadway and stopped the show each night with her rendition of “Adelaide’s Lament,” in which she complains about having a bad cold because of her long engagement to gambler Nathan Detroit. Ms. Blaine also originated roles on Broadway in “Say Darling” and “Enter Laughing.” She also starred on Broadway in “Hatful of Rain,” “Company,” and, briefly, in “Zorba.” She starred in many national tours, including “A Streetcar Named Desire,” “Don’t Drink the Water,” “Hello Dolly,” and “Gypsy.” Before going to Broadway, Ms. Blaine was a starlet at 20th Century-Fox, appearing in many musical comedy films, including Jitterbugs (1943), Greenwich Village (1944), and State Fair (1945). In the mid 1950s, Ms. Blaine reprised her role as Adelaide in the film version of Guys and Dolls (1955) with Frank Sinatra and Marlon Brando. After her Broadway appearance in “Company” in 1972, she appeared on national television at the 25th Tony anniversary special. This led to a revival of her TV career, and she continued to appear in guest roles on TV and in independent films and theater until her retirement in 1984.
