If anyone is interested, I do have Hand In Hand on DVD and am willing to make copies for anyone that would like one. The quality and sound of the movie are very good, considering that it is more than 45 years old.
I came to the Kukla Fran and Ollie site just to find this movie. I never thought I would ever find the name of it. I saw it many, many years ago, and I have never forgotten it.
