Thanks, Jazzcaz.
Your post made me go back to the piano vocal score to see how it was done in the show — or at least in rehearsals.
It's sung first by a man in G major, then goes up a minor 6th to Eb and is sung by a woman.
Here it is in Eb. It's less interesting to me than the later jazz versions.
