When I was younger, back in the late 1960's or early 70's, there was a made for TV movie about a couple whose son dies young, around age 4 or 5. At the end of the story they are comforted by a vision of their son up in heaven, and he is singing a little song he used to sing when he was with them. The lyrics go something like:
"I have got, three white stones
Whiter than any I have seen
Found in a patch of emerald green,
three white stones have I"
The memory of the little curly-haired boy singing this song popped into my head today, and I am racking my brain trying to remember the name of the TV movie. I haven't found any help with Google. Maybe someone out there remembers this?
