Pre-Broadway Tryout

Annie made its World premiere on August 10, 1976 at the Goodspeed Opera House in East Haddam, Connecticut. Kristin Vigard was the first actress to play the title role. However, the producers soon decided that Vigard's genuinely sweet interpretation was not tough enough for the street-smart orphan. After a week of performances, Vigard was replaced by Andrea McArdle, who played one of the other orphans. Vigard went on to become McArdle's Broadway understudy.

Broadway

The original Broadway production opened at the Alvin Theatre on April 21, 1977 and starred Andrea McArdle as Annie, Reid Shelton as Daddy Warbucks, Dorothy Loudon as Miss Hannigan, and Sandy Faison as Grace Farrell. It was nominated for 11 Tony Awards and won 7, including Best Musical, Best Score, and Best Book. Replacements for McArdle in the lead role included then-child actors Shelley Bruce, Sarah Jessica Parker, Allison Smith, and Alyson Kirk.
