[observation about 'Mack the Knife', 2015] I still think the definitive English language rendition hasn't been laid down. If you get to the heart of the song, the real lyrics are not the Bobby Darin version. It's this kind of of cackling ode to murder and rape and the most horrible things in society, but in a kind of beer-hall singalong style. It's the ultimate protest song, in my mind.
