I never appreciated Buddy Holly tbh but I promise you you'll love Jersey Boys Nige , it's so not really my cup of tea but , as Bivvy says , as you get older to begin to "get" stuff you tended not to appreciate as a boy/youth .
An example is the late 70's early 80's clubbing both locally & up west . I used to tag along for the tea & crumpet(s) so to speak but I could not abide the garbage I had to listen to whilst doing it.
Of course 30 years later you can't beata bita Shalamar and Kool & the Gang
