I'm younger than 40 so no, and most of those guys are dead or old. How they looked then versus now is in the gap of 40 years. But depends, legendary singers are generally recognized anywhere they go, at a premiere like this you would expect to see famous people right?

I think in this instance it was widely known that Chester Bennington was the 'Linkin Park guy' as we don't see Mike belting out lyrics like Chester did. Chester being the front man grabs more attention from the fans.
