What scenes from The Haunted Mansion did Walt Disney get to see?

We can see in the Disneyland 10th anniversary special that he showed off the stretching room as well as the paintings. He also walk passed some of the portraits in the hallway and also showed off the organ and ghost organ player. Anybody know what other scenes that came out of the mansion were under Walt’s supervision before he passed?

Marc Davis in His Own Words dates concept art (and one model mock up) for early versions of some minor gags as the grandma ghost in her rocking chair knitting, dueling ghosts, and the bicycle ghosts in the graveyard from before Walt's death.

Otherwise when Walt died the HM was in a great state of flux with it still being undecided if it was to be a walkthrough (as it was planned pre-World's Fair) or a ride. WED was just too busy juggling finishing Pirates of the Caribbean, New Tomorrowland, and the early stages of planning WDW and Mineral King Ski Resort (never built) when Walt died to be working on HM.

It’s just amazing how much effort the imagineers put into this attraction after Walt’s passing. They really just got their creative juices going and went with it within a two year timespan. There will never be as original an idea as the haunted mansion ever again in a Disney park (here’s hoping I’m wrong), 52 years young and still a smash hit.

So it seems as if walt saw everything pre-ride, the walk-through portion I mean. He saw the stretching from plus the stretching portraits and hanging skeleton as well the hallway with changing portraits and busts at the end of the hallway. The seance room, graveyard, corridor of doors, ongoing hallway were all added elements after Walt’s death.

I know that Magic Kingdom’s version of the ride was being created at the same time they were doing Disneyland’s and then a lot of the props and animatronics were put into storage. Was Magic Kingdom’s Haunted Mansion completed a while before the parks opening in oct 1971?
