"Trun" is the way Walt sang it, I learned it from him and that's the way I sing it. I think we all (moss-covered Northwesterners, that is) can trace it back to Walt. I think he learned it from Carl Sandburg's American Songbag. I don't have my copy handy at the moment, but if someone does, they can check it. Trun=thrown.
