Input: Consider Input: `` 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 . Dick Clark had advised Darin not to record the song because of the perception that , having come from an opera , it would not appeal to the rock and roll audience . In subsequent years , Clark recounted the story with good humor . Frank Sinatra , who recorded the song with Quincy Jones on his L.A. Is My Lady album , called Darin 's the `` definitive '' version . Billboard ranked this version as the No. 2 song for 1959 . Darin 's version was No. 3 on Billboard 's All Time Top 100 . In 2003 , the Darin version was ranked # 251 on Rolling Stone 's `` 500 Greatest Songs of All Time '' list . On BBC Radio 4 's Desert Island Discs , pop mogul Simon Cowell named `` Mack the Knife '' the best song ever written . Darin 's version of the song was featured in the movies Quiz Show and What Women Want . Both Armstrong and Darin 's versions were inducted by the Library of Congress in the National Recording Registry in 2016 .
