Color me wrong wrong wrong. I was talking about that with coworkers and someone said I was thinking of It's A Wonderful Life when Donna Reed is walking along singing it. I think I melded that with VL as Scarlett singing/humming in the morning after Rhett must have gave it to her good.
Can't edit. There it is for all and progeny to see: I was WRONG.
(Actually, I don't mind admitting I'm wrong but it's embarrassing. Can I play the 'getting old my memory ain't what it used to be' card?)
