Frankie Armstrong has a newer album of Brecht, Weill, and Eisler material. On this and the earlier Brecht album with Dave Van Ronk, she sings a version of "Pirate Jenny" that is powerful and for my taste more evocative than any other I've heard. She adapted her version from various translations and added some changes of her own. Perhaps the best one is to ditch Blitzstein's "black freighter" and "ship with eight sails" for "ship with black sails and 50 cannon." The 8 sails is a direct translation, but it's weak; black freighter seems to distort the whole thing. Black sails fits it perfectly, imho. And sounds like the German "acht," or 8, sails.
