This celebratory niggun was first sung at the grandstand wedding of the Belzer Rebbe’s only son Rav Aharon Mordechai in 1993 and released on the album produced in honor of that occasion Mazel Tov Beis Belz 2. From there it has traveled in ever increasing circles played at hundreds of thousands of weddings after the chassan breaks the glass as the band makes itself heard over shouts of “mazel tov ” hugs and kisses and handshakes and handclapping bochurim dancing backwards to lead the new couple away from the chuppah. “Siman tov u’mazel tov u’mazel tov v’siman tov ye-hei lanu ul’chol Yisrael.. a a a a ya ya a ya ya a ya ya ya a a a a ya ya ya ya ya yay…
Sheya Mendlowitz remembers how the tune came to him. “It was about 3 a.m. on a Motzaei Shabbos in 1993 I was up at home in New York and the tune just popped into my head. Soon I was dancing around the room to ‘Siman Tov Umazel Tov.’ I couldn’t share it with anyone local at that hour so I called Mona Rosenblum in Israel with the new song. I sang it to him a few times asked if it was any good or maybe I should just go back to sleep.
“Mona set up his answering machine to record the song so that he could play along and after playing it a few times he put me on the phone with someone who happened to be sitting with him — renowned baal tefillah and baal menagen of the Belzer Rebbe’s court Reb Yirmiyah Damen — consulting on songs for the upcoming album in honor of the huge Belzer simchah. On the spot Yirmiyah said to me ‘Sheya ich miz dus hubben — I have to have it.’ ”
