Music on Yom Ha-Atzma'ut

I have heard R. Hershel Schachter say many times that R. Yosef Dov Soloveitchik was opposed to suspending any of the mourning observances of sefirah for the celebration of Yom ha-Atzma'ut, Israeli Independence Day. So, when a group at Yeshiva University would arrange to celebrate Yom ha-Atzma'ut and would invite R. Schachter to speak, he would gladly speak but would not stay for the inevitable live music.

However, the logic for suspending the mourning customs is not difficult for me to understand. If one were to be personally saved from danger and designate a day during sefirah as a private Purim, I doubt that anyone would object to the suspension of mourning for that joyous day. Those who feel that Yom ha-Atzma'ut is the equivalent of, or even greater than, a personal Purim celebrate it as such.

The revision of the Ma'ariv service of Yom ha-Atzma'ut, though, is something that I do not understand.
