Agree. I like those! They are Disney and remind you of Disney movies that are part of Main Street's DNA, that's ok, and with Wall-E the last one qualifies. Funny how it predated WALL-E at the parks. Tony and I are big "Hello Dolly" fans as the set was a big inspiration on the DLP design. Especially the El Train idea. I tried to make DLP's MS more realistic yet romanticized and upbeat like the Dolly set. The billboards and intensely graphic ads everywhere were a reaction to that. A MS first.
As to the "showtune" issue, I was more concerned about being reminded of movies that distracted you mentally out of the moment of Main Street, where you'd recall some other movie and kind of break the spell we were trying to cast. The stuff from the movie "Ragtime" was very obscure and was from classical sources, looking back, I did break my own rule there. It was just so beautiful and perfectly captured the mood so I did it and who'd know?. It's supposed to be an "escape" and unique. I can get very purist about immersion and historic detail, but finally got used to the showtune idea. The argument was, Does it matter where it came from (we do have Star Wars and Indy) if it triggers a positive memory? I eventually got that, put them in and moved on ;-) I don't think anyone has complained either.
