I've not seen this movie in quite a few years, but there is a copy of it somewhere in my family. My dad, Jack Records, who lived in Kansas City as a child, played one of the kids in the movie (Tommy Tucker, I think, but hesitate to say for sure. He'd have been 11 years old at the time. I wish the credits had been listed here). He contacted the Disney Studios in his later life and got a print of the film. I'd like to see it again to confirm which character he played. As an adult, he became a physician (ob-gyn), spending his entire professional life in Oklahoma City. He died in 2000, at the age of 89. That his path and Walt Disney's should have crossed this way is one of our family's favorite stories.

Someone uploaded a copy of the film to YouTube, where it is currently available for viewing. My dad played the role of Jimmie Jones.
