From which opera does Bobby Darin's hit song, "Mack the Knife," come?

The Threepenny Opera (Die Dreigroschenoper) is a "play with music" by Bertolt Brecht, adapted from German dramatist Elisabeth Hauptmann's translation of John Gay's 18th-century English ballad opera, The Beggar's Opera, with music by Kurt Weill and insertion ballads by François Villon and Rudyard Kipling. The work offers a Socialist critique of the capitalist world. It opened on 31 August 1928 at Berlin's Theater am Schiffbauerdamm.

Songs from The Threepenny Opera have been widely covered and become standards, most notably "Die Moritat von Mackie Messer" ("The Ballad of Mack the Knife") and "Seeräuberjenny" ("Pirate Jenny").

Bobby Darin had gone to a theater in Greenwich Village to see a revival of The Threepenny Opera where he heard “Mack The Knife” in the show. When Darin first proposed making his own version of the song, some of his advisors and friends thought it a bad idea. Dick Clark, then popular host of the American Bandstand TV show, had become a friend of Darin’s. Clark advised Darin not to record the song because of the perception that, having come from an opera, it wouldn’t appeal to the rock and roll audience. Others agreed. Yet Darin, then 23, liked the song’s offbeat jazzy tempo. The song’s structure allowed for versatility and interpretation, and for Darin, it became a good vehicle for his talents. He recorded it in New York in December 1958.
