In the aftermath of the 1946 Kielce pogrom , vast numbers of Polish Jews left the country , including Kaczerginski , who settled in Paris . From there he toured 17 displaced persons camps in November 1947 , lecturing survivors of the Holocaust , gathering new songs , and stopping in Munich to record several pieces for the Jewish Historical Commission . During this time he also wrote several original works , including '' Undzer lid '' ( '' Our Song '' ) in tribute to Hirsh Glick , and '' S’vet geshen '' ( '' It Will Happen '' ) commemorating the British attack on the '' SS Exodus '' . His employment with the Parisian Jewish Culture Congress allowed him to visit the United States in 1948 to attend the World Jewish Cultural Conference , and he used the opportunity to take speaking engagements in 30 different cities before returning to Paris
