I thought someone might know. I am trying to download the Jeanette MacDonald/Nelson Eddy song "Ah! Sweet Mystery of Life". I got one, but it said it was Kathryn Grayson and Mario Lanza. I fifnally downloaded one thaty said is was Mac/Eddy. But I listened to it and its the same as the Kathryn one. Did Kathryn record this song, because now that I listen to it, it sounds more like Jeanette than Kathryn, but I'm not sure.
