what was the time of the greatest generation gap ever?

many would argue it was the mid-1960s, when such diverse
acts as the Beatles and TV bandmaster Lawrence Welk
were massively popular in America

despite their popularity, the Beatles and Welk shared
very few fans; those who favored one, generally scoffed
at others' tastes and life styles

the great majority of those who favored the Beatles
were below the age of 30, while those who favored
Welk tended to be above (often well above) that
generational dividing line

The Jean Shepherd Show

Shepherd's parody reflects how the younger generation
viewed Lawrence Welk and his fans
