No One Needs to Know Who Paul McCartney Is
Or possibly not. It turned out all those people asking "who is Paul McCartney?" on Twitter were just tweaking those old, grizzled Boomer noses. Kids do, in fact, for the most part, know who Paul McCartney is; they're just implying that he's not as relevant as he once was—and perhaps suggesting that the ones who are really out of touch are their elders, who may not know who West is. If that was the joke, it seems to have worked pretty well. The painful part for Boomers and their ilk, presumably, isn't just that folks don't know who McCartney is, but that it’s at least somewhat feasible that some young people don't know who Paul McCartney is. And that’s not exactly a shame.
The Beatles were hugely popular, sure, but that was more than 40 years ago. McCartney had some hits with Wings and a famous collaboration or two with Michael Jackson, but even that was three decades ago. Most pop music fans today weren't even born the last time McCartney had a song in the charts. As far as their personal experience goes, he might as well be Bing Crosby.
