Dem tog tsu gedenken (The day of remembrance) is a choral composition suitable for a Holocaust remembrance event. The lyrics were written by Ida Massey; David Botwinik set Massey's poem to music in Montreal in 1956, and created a second version in Montreal in 2008. The Chamber Singers of Haverford and Bryn Mawr Colleges under the direction of Thomas Lloyd, together with Lisa Willson, soprano, performed the world premiere of this composition in April 2012.
The translation (by Naomi Cohen, Leybl Botwinik, and Alexander Botwinik) together with the original Yiddish text and complete musical score can be found in the book From Holocaust to Life: New Yiddish Songs. See http://botwinikmusic.com.
