Only minutes into the production of "Woody Sez," words come from Woody Guthrie himself that mean everything in his world and maybe should mean everything to all of us. "Of all the places I've been and all the people I've seen, I know more about those places from the songs they sing than all the words they say." And that is the charm of the production, which opened on a freezing Sunday night in the Stackner Cabaret at the Milwaukee Rep.
