I think the discussion is moving away from the song Joe, and I do not recognise the additional verses as "communist". The verses by Woody were as I said a reminder that in nation building some will be hurt, or not gain equally through progress, but they fitted in with the ethos of the song which to my mind promoted unity of purpose. Seeger's verses were an addition to his catalogue of complaints against the country and it's system of government......a typical tactic of real Communist activists, which as an ex Party member I am well aware of. They murder a fine song.
