Donna McKechnie (born November 16, 1940) is an American musical theater dancer, singer. actress and choreographer. She is perhaps best known for her professional and personal relationship with choreographer Michael Bennett, with whom she collaborated on her most noted role, "Cassie" from the musical A Chorus Line. 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 great 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 large range. 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, remaining good friends until his death from AIDS in 1987. In 1980, McKechnie was diagnosed with arthritis and told she never would dance again. She pursued various physical, psychological, and holistic healing remedies, and was well enough to return to the Broadway company of A Chorus Line in 1986. During the remainder of the 1980s she also toured in Sweet Charity and Annie Get Your Gun, and she appeared in a London revival of Can-Can. In 2002, McKechnie starred in the pre-Broadway production of the Jerry Herman musical revue Showtune. In recent years, she has toured periodically in her one-woman show Inside the Music, a potpourri of songs, dances and anecdotes about her life in the theater and her successful battle with arthritis, directed by her old Chorus Line castmate, Thommie Walsh. Her autobiography, Time Steps: My Musical Comedy Life, written with Greg Lawrence, was published by Simon & Schuster on August 29, 2006, only weeks before the Broadway revival of A Chorus Line opened on October 5. <a href="https://www.last.fm/music/Donna+McKechnie">Read more on Last.fm</a>.
