Was that Elizabeth Taylor singing?

We were wondering exactly the same thing. From what I can find, she sang it but it was dubbed in.

That high note reminded me of the the original version of The Fly where the little fly with the human head pleaded for help in that little quivering fly voice.

I don't care what anyone says its definetly her. I even remember her joking abt her singing in an old That's entertainment! Clip, saying her singing was no threat to Judy Garland.
