I'm not sure which song about Sadako and the Thousand Cranes Tommy Sands sings, but I know of two songs about her. I think one is by Pete Seeger, or maybe he just recorded it. The other is by Fred Small. If the one Sands recorded ends with "This is our cry. This is our prayer. Peace in the world," it's Fred Small's. I don't know the Seeger song well enough to give you a line from it, and there may be others I've never heard. There are also two children's books about Sadako by the same author. One is a chapter book for young independent readers. The other is a picture book for even younger children. Both books are probably available in the children's section of most well-stocked libraries.
