By the 1960s and 1970s, rock and roll had become mainstream music, and many older people enjoyed it as well. They appreciated the energy, creativity, and expressiveness of rock and roll music, and some even adopted it as part of their own musical tastes and culture.
It's worth noting that the term "older people" is quite broad and can encompass a wide range of age groups. Some older people may have been more receptive to rock and roll than others, depending on their individual preferences, experiences, and cultural backgrounds.
