Tras muchas vicisitudes y varios intentos la adaptación de Pigmalión del Nobel irlandés George Bernard Shaw, se extrenó en Broadway en 1956 bajo el título de My Fair Lady que llevaría también la película, estrenada en 1964, dirigida por George Cukor, con Rex Harrison y la maravillosa Audry Hepburn en el papel de Eliza Doolittle, una malhablada florista callejera a la que el Coronel Hugh Pickering pretende enseñar a hablar correctamente.
Sin embargo no es la voz de Audrey Hepburn la que canta, las canciones las interpretó la soprano californiana Marni Nixon, que cantaría también en nombre de Julie Andrews en Mary Poppins, de Natalie Wood en West Side Story, de Deborah Kerr en El Rey y yo, y que aportaría las notas agudas a una Marilyn Monroe en el famosísimo Diamonds are a Girl's best Friend.
Eliza Bed! Bed! I couldn't go to bed!
My head's too light to try to set it down! Sleep! Sleep!
I couldn't sleep tonight.
Not for all the jewels in the crown!
I could have danced all night!
I could have danced all night!
And still have begged for more.
I could have spread my wings
And done a thousand things I've never done before.
I'll never know What made it so exciting;
Why all at once My heart took flight. I only know when he
Began to dance with me I could have danced,
danced, danced all night!
Servant 1 It's after three now.
Servant 2 Don't you agree now,
She ought to be in bed.
Eliza I could have danced all night!
I could have danced all night!
And still have begged for more.
I could have spread my wings
And done a thousand things I've never done before.
I'll never know What made it so exciting.
Why all at once my heart took flight.
I only know when he
Began to dance with me.
I could have danced, danced danced all night!
Mrs. Pearce I understand, dear.
It's all been grand, dear.
But now it's time to sleep.
Eliza I could have danced all night,
I could have danced all night.
And still have begged for more.
I could have spread my wings,
And done a thousand things I've never done before.
I'll never know What made it so exciting.
Why all at once my heart took flight. I only know when he
Began to dance with me I could have danced, danced,
danced All night!
