The designers may have felt the song didn't fit well with the scene ( or scenes ) they were planning as the Attraction went through its lengthy design phase.
It's like making a movie, in that you plan a lot of scenes but in the end you end up cutting a few out.
It must have been planned to be included or they would not have bothered to record the demo I've heard.
In a way, the version of the song recorded for the DL Attraction expressed hope and belief that Brer Rabbit would return home.
So it was a tune reflecting 'hope'.
It was probably decided that within the context of the ride experience 'story' that a more threatening tone was needed to be felt in a scene before the final plunge to create some anxious foreshadowing.
Thus the more foreboding tune sung by the parent critters to their young'uns in the DL Attractions pre-final lift hill scene for given precedence over using the 'Sooner or Later' tune.
It does the job well within the context of the scene....that other 'lamenting' song.
The song lyrics warn of the dangers to come if one wanders off to the Laughing Place...which fits the 'story' of the ride perfectly.
You need to create a bit a tension before the 'big plunge', exspecially after the happy goofiness and glee of the previous 'Laughin' Place' scene.
I found it interesting how that 'warning of danger' scene with the parent critters and their young was only used in the Original at DL.
It was not carried over to other versions of 'Splash Mountain'.
So my thoughts besides those..?
It's nice to have a unique scene in the DL version , that creates a sense of danger to come.
WDWs has a quick moment pre-final drop with Brer Fox gloating over the capture of Brer Rabbit, but it does not create the same sense of foreboding doom as the DL version does in my opinion.
What is interesting though is that when I am riding WDWs version of the Attraction, I don't miss DLs 'lamenting' scene at all within the context of experiencing the ride.
WDWs version is a completely different experience to me.
A whole different animal.
The pacing is different, the scenes more fleshed out and complex, and even the drop seems different ( slower compared to DL ' bullet shot' ).
So while it makes me curious as to why that 'lamenting' scene was not included in the WDW version, I am perfectly happy with it being a 'Disneyland Exclusive'....just like the entire rides soundtrack!
