Hack went through many phases where he thought that playing a musical instrument would make him irresistible to women. The concertina era was probably the most disastrous where he would confront random women frantically pumping the bellows (which he had no concept of how to actually play) and then proposition them sexually, inevitably receiving a brutal beating from their male companions or from the women themselves (often both). He wrote this highly idealized novelization of the experiment in which the fictional version of himself was infinitely more successful with the ladies than he was in real life.
