So unless my ears deceive me...Splash Mountain and the related characters are not the only Song of the South influences in the park. Take a listen around 0:40 in this video.
Not the most interesting topic ever discussed on MiceChat, but I never realized that before.
(Also...hopefully, the fact that this video can't simply be bought from Disney will convince the mods not to remove the video link. If not...I get it. )
