Nixon's "I Could Have Sung All Night," which she co-wrote with Stephen Cole, is due in stores this month from Billboard Books. On Sept. 10 the acclaimed singer-actress will appear with Cole at The Drama Book Shop at 2 PM, and the duo will also be on hand to autograph copies of their new tome Sept. 18 at 7 PM at the Barnes & Noble Lincoln Triangle.

Nixon is perhaps best known for dubbing the vocal performances of such film stars as Audrey Hepburn (in "My Fair Lady"), Deborah Kerr (in "The King and I") and Natalie Wood (in "West Side Story"). In "I Could Have Sung All Night," she recalls her numerous Hollywood and Broadway experiences, including working with Julie Andrews, Leonard Bernstein, Liberace, Cary Grant, Otto Preminger and Victor Borge.

Marni Nixon was most recently on Broadway in the Tony-winning revival of Nine, and her other Main Stem credits include Follies, James Joyce's The Dead and The Girl in the Pink Tights. She played Aunt Alice in the film "I Think I Do" and Sister Sophia in the motion picture of "The Sound of Music." Nixon was recently seen as Mother Abbess in the Hollywood Bowl's presentation of The Sound of Music.

Nixon's hardcover autobiography, which features a foreword by Marilyn Horne, retails for $24.95.

The Drama Book Shop is located at 250 West 40th Street. Barnes & Noble is located at 1972 Broadway at 66th Street. Admission to both events is free.
