It was approximately 1960, I was listening to the radio in my Dad's car; I only heard the song once and I can still remember some of it; I never heard it again, but it went:

Mommy, mommy come and see Answer if you can Why can't it be just like it was before the war began

Come away Melinda, come in and close the door, the answer lies in yesterday before they had the war

Any ideas???
