Dear Senator Muskie: The New York Conference on Soviet Jewry, a coordinating committee of the local New York chapters of the major national Jewish organizations, will be conducting a demonstration for Soviet Jewry on Thursday, October 2nd, at 6:30 P.M., at the United Nations. The demonstration, which will be called a Simchat Torah Celebration, will be held to express solidarity with the young people in the Soviet Union, who each year have been congregating at the large synagogues in Moscow and Leningrad, to dance on this joyous holiday, as an expression of their Jewish identity.We would be most honored if you would lend the prestige of your office and your name to our program and deliver the major address. We hope your schedule can be so arranged, and would appreciate it greatly if you could let us know as soon as possible, so that we can make the necessary arrangements for our publicity and for invitations for the thousands of people who will be there.If there is any additional information that you require, please contact me at my office — (212) PL 1-4000. Thank you.Sincerely,Rabbi Norman Lamm, ChairmanN.Y. Conference on Soviet JewryDavid Geller, CoordinatorN.Y. Conference on Soviet Jewry
