Careful with money - "tight" - "Jewish?"

I've just been watching a light-hearted programme on Channel4 entitled The Hunt for Britain's Tightest Person, the object of which was for the presenter to try and find the person in Britain who is not only 'careful with money', but is possibly the most careful person with money in the country or, in colloquial parlance, 'tight' or 'mean'. All very frothy and amusing, perhaps even with things for people like me to learn in these more straitened economic times. However, one feature I found curious and disappointing from a 'right on' channel like Channel4 was that the soundtrack playing throughout the programme was what can only be described as Jewish[Yiddish]-style folk music, played on an accordion. it really seemed to be, presumably unconsciously and with no desire to offend, harking back to some pretty unpleasant stereotypes about one particular ethnic grouping, by its choices of music, to provide the 'atmosphere' for this programme. A good and interesting short programme, but I must record a black-mark against it because of this.
