Hi :). Paul Robeson sang it, he was a great singer- songwriter and a good person, but he was a communist who McCarthy was after as well. That idiot wanted to execute Robeson >:(.

You can find it on youtube, there are many videos of it with lyrics as well, if you would like to learn the song.

Anyway, this was the first song I ever heard, my father sang it to me when I was in the womb xx Great song :)
