With the closing of the scroll on the grave of the late Rabbi Shmuel Azimov on the Mount of Olives, the participants began playing the melody "Ha'aderet Ha'Amunah" to the tune of "La Marseillaise" - the French anthem composed at the height of the French Revolution - which the Lubavitcher Rebbe taught during the fourth lap - on the night of Simchat Torah in 1934.
The Nigun is identified in Chabad Hasidism with the 'Jewish Revolution' that the movement brought about in French Jewry - a revolution led by the late Zt"l from the days of his youth until his last day, as the Rebbe's chief emissary in France, in which tens of thousands of French Jews came closer to a life of Torah and mitzvot.
