Here is another interesting story.
I guess society suffered because those poor, benighted villagers stopped practising their own good culture.

"The following, perhaps related story, was told to me 40 years ago by a famous musicologist whose son was a musico-ethnologist. The son attended a conference where one of the more exciting papers was given by a man who had succeeded in reaching an isolated South American Indian tribe, never before visited by white men with a battery operated tape recorder and recorded their music. When he played the tape, one of the audience caused a disturbance by jumping up and shouting, 'Those are Polish Jewish Hassidic melodies.'

The story becomes more interesting when the researcher presented a paper a few years later in apology. The new story, prompted by the reference to Hassidic melodies, was as follows. One of the older Indians remembered that some 60 years earlier a peddler had come to the village and was trapped there for a long time, more than a month, perhaps even as long as two. At that time, as they warmed themselves, taking shelter from the rain, he would sing to them and teach them his songs."
