I learned this song from my much-older sisters in the mid-60's. They didn't like to sing it to me because it made me cry, but I loved it, anyway. When my children were born I remembered all that I could and sang it to them that way. I have just played one of the above piano renditions, and my younger one, age 17, says it's wrong. But what does she know? I taught it to her wrong! Thanks for the extra words, everyone, so I can sing it "wrong to my grandchildren, someday.
