I stumbled upon this film while looking for something completely different. Today's "nibble" was going to be a recording of "Go Down, Death" by James Weldon Johnson ... But in the pursuit of a suitable clip, I ran across this, and had to switch gears. Song of Freedom stars Paul Robeson. The film captured, for Robeson, at least some small part of what he wanted to do in his work, to give "a true picture of many aspects of the life of the coloured man in the West."
"Hitherto on the screen," Robeson said, "[the coloured (sic) man] has been characterized or presented only as a comedy character. This film shows him as a real man."
