* AdaptationDisplacement: Only [[OverlyNarrowSuperlative aficionados of Augustan English drama]] would recognize the source material. Though this might have been different when the opera came out in 1928 Berlin, because ''Theatre/TheBeggarsOpera'' had just seen a revival there.
* CoveredUp: Bobby Darin's rendition of "Mack the Knife".
* DracoInLeatherPants: Macheath is the one character most audiences seem to like best, even though he is intended as a despicable villain.
** Though of course most productions water down the violence and nastiness of the original a lot, if portrayed the way Brecht wrote him - an amoral pimp, human trafficker and child murderer - this trope is less in play.
* EightDeadlyWords: All of the characters are intentionally unsympathetic.
* OlderThanTheyThink: Several of Macheath's songs are taken from the French renaissance poet (and professional criminal) Francois Villon. It works in the other direction, too: A lot of people are more likely to connect the "Moritat" with Bobby Darrin or Louis Armstrong than Bertolt Brecht.
* WordOfGay: Yes, Brown loves Mack.
