At a farbrengen, the Rebbe sings the nigun Becho Botchu, with the words from Tehilim 22. Circa 1979.
This nigun was sung by the Chassidim of Dokshitz (Russia), and was introduced in the United States by the Chassid Reb Yochanan Gordon of Dokshitz.
Lyrics: Bechah Botchu Avoseinu Batchu Vatfalteimo Eilecha Zo'aku Venimlatu Bechah Batchu Velo Boshu.
In You our fathers trusted, They trusted and You delivered them. They cried unto You and they were rescued, They trusted in You and were not ashamed. Chabad.org
