With all due respect, there area number of errors in the above post.
For example, "Solidarity Forever" is a song about the fact that all the world's wealth is created by working people and really belongs to them - it wasn't an anti-war song, per se.
I don't believe Ralph Chaplin ever intended to ask Joe Hill to finish "Solidarity Forever" - he was a pretty capable songwriter himself- and the "illness" Joe Hill died of was being
wrongfully executed by the State of Utah in 1915 - the year Ralph Chaplin wrote the song.
So, it's good that you like the song but I just wanted to point out a couple of things that you misunderstood.
