François Villon’s 15th century French songs and John Gay’s 18th century English “Beggar’s Opera” are among the sources Bertolt Brecht and Kurt Weill used to create Die Dreigroschenoper, a musical play that premiered in Berlin in 1928. It won fame in English as The Threepenny Opera, and its songs “Die Moritat von Mackie Messer” (“Mack the Knife“) and “Seeräuberjenny” (“Pirate Jenny“) are widely known and sung. The original German score joins the public domain in 13 days. #PublicDomainDayCountdown
