I saw a mention on Wikipedia recently that one of the characters sang a Yiddish or Hebrew song, so I thought I would give it a try.
This is what used to be called a “race” picture. It was an all black cast made by a black director. Unfortunately it is probably most approachable as a sociological specimen rather than as entertainment. The acting is extremely bad. So much so that I decided to fast forward to the musical numbers. The singing and dancing are passable, but not great. The sound is extremely bad. This may be the result of using first generation equipment. By 1938 sound was a relatively mature technology, and even B pictures, like the Boston Blackie series, or films made on poverty row had decent sound.
I never did hear the Yiddish song. Avoid, unless you’re taking a class.
