This is the voice of Eliza Dolittle in "My Fair Lady." This is who you heard in "West Side Story" as Maria. And she is also the voice behind Anna in "The King and I."
She is Marni Nixon, the woman whose voice supported Audrey, Natalie and Deborah in the musical film roles. I've only seen Marni in a little (singing) role as one of the nuns in The Sound of Music, complaining about the problem (like Maria.)
Now 77, Mrs. Nixon is in the New York Philharmonic’s concert-style revival of "My Fair Lady" at Lincoln Center this week.
Here's the story.
