Maybe the name needs some work... I'm usually horrible at naming things (for the show, not the theater. I like that name ). And I originally posted this in the Disneyland Tracker thread, but later decided to move it into it's own thread, thus keeping that one on-topic.
I'm working on an idea now, that would entail the complete removal of the Carousel Theater, in Tomorrowland, with that space then available for a new attraction. Then, in Frontierland, the Big Thunder Ranch and Festival of Fools Arena would be torn out, as well. I would then replace them with a larger (albeit, not much larger, according to Google Earth) Carousel Theater, now called the Wagon Wheel Theater. It would be placed underground, with a queue/ramps leading down to the loading area (starting top-side in a barn), and ramps leading back up to the surface, coming out of a hole in the wall of a jail cell in a small jail/sheriff's office.
The show would consist of 6 scenes, like the original shows in TL had, but because of the larger space, would have an even higher capacity, and more room for the stage section, as well. The show would start off in an underground mine, where a miner would come out of a small cave in a mine cart to introduce the show. Each scene thereafter would represent a different locale in the U.S., around the timeframe that Frontierland takes place in, allowing for the greatest range of songs to be chosen.
The next scene would be in the Midwest, playing up prairie-type music. After this scene would be the Southern U.S., specifically the mountains of the South. This part would be very familiar to all who ever experienced the Country Bear Jamboree. A slightly modified version of the old stage design and layout would be used, and some of the songs from the original show, and some newer ones, would be utilized.
The next region to be explored would be the Wild West, in the deserts. Cowboy and desert music will be featured here. The next scene takes a page out of Marc Davis' book, and Disney history: it would take place in a small Western town, playing the more popular songs of the old-frontier, culminating in a little bit of a shoot out/bar brawl scene (a la Western River Expedition's grand climax).
Each scene would be introduced by the Miner host, as well as a host for that scene. Also, this would be true at the conclusion of each scene. The final scene would have all of the different hosts from the show (The Miner, Henry from CBJ, and the others, who have yet to be determined), giving us one last musical number and a final farewell, extending the invitation to come back again.
On the surface, would be a Western Settlement in the middle of the wilds of the frontier's forests. With the main attraction being underground, there is now room for other attractions to be installed up top- a D-ticket, and maybe one or two C-tickets (again, utilizing stacking attractions on top of eachother to maximize space, similar to Alice and Mr. Toad), plus a store and a new restaurant.
The concept is not finished (obviously), but well on it's way, I think.
