Chabad Chassidim would traditionally gather during Simchas-Bais-Hashoeva for a farbrengen, where Torah and inspiring talks would be discussed and that would lead to song and dance. Among other Chassidim, the joy of Simchas-Bais-Hashoeva would be expressed through singing and dancing.
In recent years, we too have been placing more emphasis on actual singing and dancing in celebrating Simchas-Bais-Hashoeva. One of the reasons for this is, because we want to bring about greater unity among different circles of the Jewish people. This can be accomplished by introducing more music and revelry (without minimizing the original emphasis).
This joy of Simchas-Bais-Hashoeva must also be taken out to the streets.
Appropriately, we find in the Haftorah of the first day of Sukkos (Zechariah 14:16): And it will be that all who survive from the nations who came against Yerushalayim will go up year after year to bow down to the King, the L-rd of hosts, and to celebrate the Festival of Sukkos.
The prophet goes on to speak of the evil that will befall those who do not celebrate the festival of Sukkos. From which we can understand that the reward for those who do celebrate Sukkos will be very great. This is comparable to the non-Jews who today assist and join us in our celebration of Simchas-Bais-Hashoeva.
Indeed, it may be said, that this is a preparation for the ultimate promise: For then will I turn to the people a pure language that they may all call upon the name of the L-rd to serve Him with one consent (Tzephania 3:9).
For us it is surely significant. For although G-d chose us from among the nations and in that sense we are beyond comparison, yet we say in the prayer of Yom Tov: You have raised us above all tongues, even in those areas where we can be compared, G-d has raised us above all other nations. . .
May it be G-d's will, that you will all increase in all your deeds along these lines and especially in the action of the joy of Simchas-Bais-Hashoeva - more song, more clapping and dancing. And just as in the korban Pesach the women were included, so too, in this simchah women should also participate (in separate groups).
As we will increase the joy of Simchas-Bais-Hashoeva while we are still in the golus, so should we merit to celebrate the joy of the Simchas-Bais-Hashoeva in Sukkos, this year, in our Holy Land, the true place of the Jewish people, with the true and ultimate redemption.
And in our Holy Land we should be in the holy city Yerushalayim in the Third Bais Hamikdosh where we will all see the revelation of G-dliness. May we leave the golus in unity and completely - and while still here may we merit to receive an abundance in physical and spiritual blessings.
The main thing, we should immediately merit the true and complete redemption, when the promise we read on the second day of Sukkos will come true, "The L-rd shall be king over the entire earth." And then: "It will be that all who survive from all the nations who came against Yerushalayim will go up, year after year, to bow down to the King, the L-rd of Hosts, and to celebrate the festival of Sukkos." With the coming of our righteous Moshiach, quickly and truly in our days.
(Sichos of Sukkos 5746)
