But, you do have to admit that any of the old fables or stories are made much more well-known and kept in the public eye by getting the Disney treatment. I don't necessarily think they would die out completely, but Disney does give them a very big shot in the arm.
To the extent the stories were given a shot in the arm by Disney, it was still the Joel Chandler Harris version of these stories. If they wanted to focus on the African version of these stories, they could have set the movie and the ride IN AFRICA, instead of in the Reconstruction South. I'm sure yes, awareness Song of the South and the Joel Chandler Harris versions inspired more interest in the original stories the Uncle Remus stories were derived from, especially as more black people were allowed to attend college and studies of non-Western traditions grew in popularity, but those efforts won't be harmed in the slightest by Disney re-theming a theme park ride.
