There's a lot of bands that get to a certain level, and it just stops. They scrap it. Compare this to, say, The Rolling Stones or The Who, where they just continued on forever and are still playing, or they quit after 20 years.

These days, the Rolling Stones still have an edge, but that fangs-out ferocity has mellowed considerably.

If you're the Rolling Stones, you can sing 'Start Me Up' for 35 years, and people still cheer.

You've got the sun, you've got the moon, and you've got the Rolling Stones.

I've done the Rolling Stones eating each other.

...it was not simply a matter of musical taste; whether you preferred the Beatles or [the Rolling] Stones said much about your personality and character. People who were happy, intelligent, well-adjusted, popular, clean, decent and punctual tended to be Beatles fans. Those who were evil, cretinous, scabby, drug-ridden, filthy, criminal perverts liked the Stones.
As for your author, I personally take no side in the controversy, remaining strictly neutral.
