Here's an interesting
J Post article about Kol Nidre. Here are the first 'graphs:
When Reb Leizer of Czenstochow walked out of the gates of Buchenwald, he set out to find his youngest son. In the last moments of deportation he had thrust the child into the arms of gentiles - perhaps he was still alive. In his old town, he was told to try the monasteries. Not surprisingly, none of them admitted to sheltering any Jewish children.
Reb Leizer bought an organ and added one melody to the stock of marketplace ditties: Kol Nidre. He moved about the countryside as an organ grinder, setting up his instrument in each village and watching as children ran to hear his music. Whenever he played Kol Nidre, he would observe their faces for any reaction. Sometimes, he saw signs of recognition, of sadness and longing. He would follow these children, take them aside and tell them: "The war is over. You can go back to your own people."
According to the story, Reb Leizer never did find his son, but he helped dozens of Jewish children regain their faith.
