That would seem right to me. We don't associate her with being a singer. The question is who usually dubbed her?
That's a good question. We've known about Marnie Nixon for years, but I'm sure there were many unheralded singers who were expected by the studios to just sign the contract, do their turn in the recording studio and pick up their check, no questions asked. It seems like a great line of research for someone who could unravel it all. I'm assuming that research doesn't already exit or Terrence wouldn't have to ask this question in the first place. Personally, I don't think it would tarnish the images of major stars to know they were dubbed; it would give long overdue credit to some very talented people unknown to the public.
