I need a quick reference for lecture purposes. The story about Jean Hagen dubbing Debbie Reynolds extradiegetically--is it really true? Where would I find a reference to that? I have been repeating it all my life and now that I have to say it to 150 students I am doubting whether or not it is true. Did Hagen really sing the parts that Reynolds was supposed to sing for the character Hagen portrays? Thank you, Gloria Monti
