On the last night of Chanukah, a bunch of guys came together and sang with Yigal Calek, legendary director and conductor of the London School of Jewish Song, a Jewish musical phenomenon of the ’60s, 70s and 80s.

In an attempt to explain this extraordinary reaction, Rabbi Dunner turns to the Igra Dekalla, and an insight he proposes for a challenging passage in Parshat Vayigash.
