In Chassidic Israel, a Bar Mitzva is very simple. We don't make tremendous receptions in lavish halls. The Bar Mitzva boy puts on his new tefillin in the morning and gets called up to the Torah (if it's a Monday or Thursday). In the evening, we have a festive meal with family and friends, and sometimes a musician, and the Bar Mitzva boy gives a speech, usually a Talmudic elaboration with an important ethics message. The budget is very low but the joy is very high. Here's a clip from the Bar Mitzva of my grandson Yaacov Yosef, the son of my first-born, Rabbi BenTzion Brody of Jerusalem. Enjoy it and have a wonderful Shabbat!
