Yud Beis Adar is the Yohrtzeit of Harav Yitzchok DovBer Ushpal, o"h, late Rov of Boro Park's Anshei Lubavitz shul. Here are some recordings as well as writings of his. He left no children. He is pictures 3rd from left in the picture below, which is a group shot of talmidim of the Tomchei Tmimim Yeshivah in Vilna c. 1940. Also seen above of Rabbonim Weinberg and Greenglass, oleihem haSholom.
I thanks those who sent me the clips, as well as the respective websites from which the writings and picture were taken. Being from the Vilner Gubernye you can hear the Rov's Litvise "sin" very clearly. The nigunnim are sung with a somewhat different, more elongated kvetch than what we're used to today.
