With a smooth - and - smarmy singer and a big - band horn section that 's ten years out of date ? It 's a pretty ballsy move . Even more ballsy is Darin 's decision to insert the name of Lotte Lenya - Weill 's wife and the best - known interpreter of his songs - into the list of Mack 's victims . Whether it actually works or not I could n't quite say .
According to the above context, answer the following question.
What may be the reason for all of these " ballsy " moves ?


For publicity .
