A fascinating Crossover this week, as Jill's guest is the voice behind the faces of some of Hollywood's most important musical stars. Marni Nixon has "ghost-sung" for Deborah Kerr in The King and I, Natalie Wood in West Side Story, and Audrey Hepburn in My Fair Lady to name a few. She has just written an autobiography that is spellbinding and Jill speaks with her about her life in music and films.
