I loved this story as a child - it offered so much more to think about than . . . "Goldilocks and the Three Bears" for example.

I don't usually care for children's movies anymore, but will definitely go to this one.  It's very nice that Grace is associated with it, and she makes a fetching Rapunzel in the picture above.  Doesn't matter what song, I'm sure they'll make it fit nicely.
