Sheyiboneh Beis Hamikdosh

Therefore, when a grand Siyum Sefer Torah was held at a ballroom in Manhat tan, in conclusion of the first Sefer Torah Hakloli on Lag Baomer 5742, Chazzan Zalman Baumgarten chose to sing this song during the event. Later on, a video of the event was shown to the Rebbe.

Because Lag B'omer was not on Sun day, a parade was not held that day, and instead a Tzivos Hashem rally took place in 770 later that day.

After the pesukim had been recited the Rebbe spoke a number of sichos for the children present. At the conclusion of the third sicha, the Rebbe explained that this kinus was to be connected with Torah, Tefila, and Tzedaka. The Rebbe then continued to enumerate how each one was to be fulfilled.

The Rebbe explained how Tefila was to be done:

"At the end of the kinus, the children should recite the tefila that is connected with Geula: Yehi ratzon milfonecha Ha shem Elokeinu v'Elokei avoseinu sheyibone beis hamikdosh bimheira biyomenu (now!) v'sein chelkeinu b'torasecha...

...They should say this tefila with a song the song on these words which is well known amongst most of B'nei Yisroel, because in addition to the words belonging to every Yid, the tune also belongs to every Yid."

Chazzan Moshe Teleshevsky relates:

"After the sicha during which the Rebbe mentioned singing the niggun Sheyibone in the tune which is well known amongst most Yidden, many understood that the Rebbe was referring to the famous song which begins with a piece of Chazonus. Realizing that the Rebbe wanted this sung shortly there after, people began searching for me, as I was often the Chazzan in 770.

"While Rabbi J.J. Hecht translated the previous sicha, people searched high and low, however they could not find me because I was not in 770 at the time.

"A Bochur ran out of 770 in search for me, and located me a block away from 770. I hastily followed him to 770 and went up to the stage that had been set up on the Rebbe's Farbrengen Bima."

Rabbi Hecht immediately quieted the children and instructed them to listen quietly to the Chazzan singing the first part of the composition. As he continued into the second and more well-known stanza, all the children burst into song - "Sheyibone Beis Hamikdosh..."

Although the niggun was typically sung at a slower pace, the Rebbe began to clap along to the niggun, raising the momentum with every round that the niggun was sung. Within a short time, the main shul of 770 resounded with the exuberant strings of the newly introduced niggun.
