Reb Michoel's Niggun
This Niggun Chabad was originally sung by Reb Michoel Teitelbaum A"H to the famous Ba'al Menagen Avrem'l Charitonov (from crown heights).
Reb Michoel's father, Reb Chaim Moshe, was a Chossid of the Rebbe Rashab.
One year on Simchas Torah the chassidim were dancing in shul for Hakofos in a circle and he was dancing in the middle. The Rebbe Rashab joined the inner circle and put his hand on Reb Chaim Moshe's shoulder and danced with him for a period of time to this Niggun.
