I have had a song in my head for days, and I can't remember much about it. To date this critter, it was on AM radio in the days when I'd clip an alligator clip with a wire attached to a cylinder with an antenna on it( a crystal radio, if I remember, 1958) or so. It concerned a child (boy girl?) on a subway track with the light of the train bearing down on him/her. The brother/sister is calling, trying to save. I know this is not much, and searching the net has gotten me nowhere. There are enough folk of my vintage here that this may tickle someones memory. I seem to remember it more as popular rather than folk, certainly not trad. Any help or clue would be not only appreciated, but the first. Thanks, Mike
