I would also consider choosing more modern songs (the argument that the teacher has been singing it for almost forty years, I really don't find convincing why they should sing it). I would let them choose to bring notes, lyrics to songs that she likes, so that we can use them to intersperse the set of obligatory folk songs that they should know. Especially in music education, I would let students express themselves, actively participate in their ideas, relax, express emotions, taste, create, etc.
