Who all has sang Sleeping Beauty "Once Upon A Dream"?

We were watching Cartoons this morning with my children and a Sleeping Beauty cut came on where she was singing "Once Upon a Dream" and my wife asked me who it was that was singing it. I have done some research and found that it is not Emily Osment (2008) and it is not Mary Costa (1959). It has to be somewhere in between. It sounded like Judy Garland but I could not find where she had sang it. Thanks
