The oldest performer was 104 years old, while the youngest was 3. Researchers were divided into seven regional crews. The campaign was supported by Polish Radio, which provided production trucks. The first stage of the research was led by students and other young people. They asked around for famous local bands, and searched for grandmas who knew a lot of traditional songs. Jadwiga Sobieska instructed the researchers:
You constantly have to search, ask questions and talk with people. You have to stop by whenever you see a granny by a fence, people on the field or older children.
Then, another group of researchers came and examined the situation, chose the musical pieces and recorded performances. The most exciting part was usually the arrival of the production truck:
People were delighted and curious to see us, they thought we were a circus troupe, cinema, or even a boxing team. When we arrived in a village, children would run towards us, shouting 'No matter the cost, we're going!' (they thought we were a circus show). An hour or so later, we already had our first volunteers ready at the microphone.
They recorded in cottages, at rectories (although some singers refused to perform some pieces in church, such as courtship serenades), in schools, and outside: by the roads or next to grazing cattle.
Usually, they began their sessions in the evenings, when people came back home from the fields. Until the late hours, 'the cottage was filled with supporters.' Singers and bands fought for the attention of researchers. As all Polish wedding musicians know, drinkers make the best singers. In effect, the researchers constantly had to provide refreshments for the performers.
Unfortunately, musical abilities flourish in a vivacious atmosphere. [...] The musicians are usually well-acquainted with the cult of Dionysus and they either play great when inebriated (then our contribution pays off) or they can't even find the right sounds, which destroys all of our hard work. In such moments, we immediately have to take charge of the situation and interrupt their little concerts (due to things such as technical issues). It's especially important because the room is usually filled with advisers and supporters, whose 'co-operation' boils down to drinking or encouraging others to do so. Most often these situations come to the point where the gathered men compete with each other to perform the most explicit song possible [...].
