Who wrote the music to the song 'Mack the Knife'?

"Mack the Knife" or "The Ballad of Mack the Knife", originally "Die Moritat von Mackie Messer", is a song composed by Kurt Weill with lyrics by Bertolt Brecht for their music drama Die Dreigroschenoper, or, as it is known in English, The Threepenny Opera. It premiered in Berlin in 1928 at the Theater am Schiffbauerdamm.

"Mack the Knife" was introduced to the United States hit parade by Louis Armstrong in 1956, but the song is most closely associated with Bobby Darin, who recorded his version at Fulton Studios on West 40th Street, New York City, on December 19, 1958 (with Tom Dowd engineering the recording). Even though Darin was reluctant to release the song as a single, in 1959 it reached number one on the Billboard Hot 100 and number six on the Black Singles chart, and earned him a Grammy Award for Record of the Year.
