Not sure who wrote it. Earl Robinson possibly. Pete did do it on one of his _Broadside_ LPs for Folkways.Check out the current issue of Sing Out! An article on Paul Robeson by the grand old editor of Sing Out, Irwin Silber. Great to see him in print again. I suspect the song was in the People's Songs Bulletin.
The riot at Peekskill was over a concert by Mr. Robeson.
