Readers who’ve been following Jewish music long enough (or are old enough) might remember Mordechai Ben David’s very first album release, back in 1973. Titled Mordechai Ben David Werdyger Sings Original Chassidic Niggunim, the album’s impact was understated, and most of those original chassidic niggunim never really took off (except for two songs — “Yosis,” which MBD revamped in 1988 for the Jerusalem Our Home album, and “Hashiveinu,” which, with a revised beginning, became a popular dance and camp song in the 1970s).
