During the frightfulness of World War II, Irena Sendler and the 20 or so others in the organization she created managed to save some 2,500 Jewish children, many from the Warsaw Ghetto. She was caught and tortured by the Gestapo, condemned to death, managed to escape and went right on rescuing Jewish children until the war's end. She died in her native Poland in May of this year, at the age of 98. On January 6, the Ra'anana Symphonette, conducted by Omer Welber, presents the world premiere of Irena's Song by Kobi Oshrat for orchestra, voice and violin. One of the singers is seven-year-old Shalev Menashe. The performance will be held at the Ra'anana Municipal Auditorium.
