Mendy Jerufi got together a bunch of Chabad singers, including Simche Friedman, Nemouel Harosh, Yoni Shlomo, and Yisrael Jerufi to refresh an old Chabad niggun, as part of Jerufi‘s project to increase awareness of Chabad songs. The song is called Ki Rega B’Apo, composed by R’ Avraham Lisson A”H. The track was arranged by Moshe Laufer.
