I seem to remember that Rosalie said she got the basis for the song from a poem by Olive Burt (not too sure about that name, and can't locate her book nor Rosalie's record, but I think that's right, that she started with that poem). I'll have to write to her...why doesn't everyone have email??? But I'd love to find out more about the ad, and which came first, the song (or poem) or the ad. Jean
