TLS, one page both sides, 5.75 x 7.75, personal letterhead, May 11, 1961. Letter to Howard Weiner, in part: "I am sorry I am not able to send you the requested songs for the very simple reason, that I don't have time. You might get them at the publisher in Vienna…As far as the different versions of Mahagonny and Dreigroschenoper are concerned, it would take me too long to explain. But that much I can assure you, they are all authentic and no injustice has been done. Brecht kept changing from stageversion to bookversion till the very last moment. But all this will be explained in K. Weill's biography, which is in the making." In fine condition. Accompanied by the original mailing envelope and the three-disc LP box set of Kurt Weill's Rise and Fall of the City of Mahagonny, released by Columbia Records in 1956.
