David's Promises, Promises, choreographed by Bennett. Along with Baayork Lee and Margo Sappington, she danced in one of Broadway's most famous numbers, "Turkey Lurkey Time", which was when she first began to attract notice from critics and theatergoers alike. This was followed by a role in the touring company of Call Me Madam, starring Ethel Merman. Bennett showcased McKechnie again in Stephen Sondheim's Company (1970), where she danced "Tick-Tock". After leaving the Broadway cast, she reprised her role in the Los Angeles and London companies, and also toured in the 1971 revival of On the Town as Ivy. In March 1973, she choreographed and performed in the highly acclaimed one-night-only concert Sondheim: A Musical Tribute at the Shubert Theatre in New York. In 1974, she co-starred with Richard Kiley and Bob Fosse in the unsuccessful musical film version of the classic The Little Prince. McKechnie was part of Bennett's group therapy-style workshops that evolved into the Broadway smash A Chorus Line, in which she portrayed Cassie, a character based in large part on herself. She danced her third famous Bennett-McKechnie number, "The Music and the Mirror", in which the vocal sections were tailored to her unusually wide range. Initially, Donna was to perform the number with four of her male co-stars; however, four previews before opening, McKechnie voiced concern about dancing around the four men, and at the last moment, Bennett changed the direction to have McKechnie perform the song-dance number alone. Her performance earned her the Tony Award for Best Actress in a Musical. The role of Maggie was also based on her life. She married Bennett in 1976, but after only a few months they separated and eventually divorced, although they remained good friends until his death from AIDS in 1987. In 1980, McKechnie was diagnosed with arthritis and told she never would dance again. She went on to choreograph NFL's Football's Fabulous Females, The Los Angeles Raiderettes in 1983 as they made their debut in L.A. The same year, in season 2 of the TV show Family Ties, she played Cynthia, a divorcee who planned to move west with her young son away from his father. McKechnie pursued various physical, psychological, and holistic healing remedies, and was well enough to return to the Broadway company of A Chorus Line in 1986. Later in the 1980s, she toured in Sweet Charity and Annie Get Your Gun, and she
