what's the deal with bob dylan????

so, this morning, we're listening to an old tape steve has... some amnesty international concert... the police (the last time they performed as 'the police' no less) and u2.
 
u2 covers a bob dylan song... something about maggie's farm or something. i dunno... anyway, the crowd is going effin' NUTS...
 
i asked harold why people like bob dylan. i just assumed he did because he likes the oldies and the classic rock. he didn't know. (thanks, harold... thanks for nothin'!) he said he wasn't really a big fan of bob dylan. he assumes the people of that generation like him because it reminds them of "a simpler time" ... okay. sure... i could buy that... but ... what about the people who didn't grow up with him and still love him?
 
i just don't get it.
