I've just downloaded from iTunes one of my favourites. It is called Chorra, which I think means Thief; you can hear it here, and then if you close the file you will find the complete lyrics. These are in Argentinian Spanish with some words not in the dictionary and I am not at all sure that I have grasped the plot. I think the singer is complaining about some evil character who has stolen his wife: he describes him as like an ...agente 'e la camorra, ...malandrin y estefador and as ...profesor de cachiporra. That last word is in the dictionary and I take the phrase to mean that he is an expert with a cosh, but then my Cassell says that cachiporra is a stick with a big knob, so perhaps I am missing the point.
I would welcome any comments from speakers of Lunfardo.
