Celebrity Autograph

There was a crowd of people in front of the stage entrance to the David Letterman show, and when a large Escalade pulled out, suddenly a surge of people started chasing the car.  Unfortunately the light at the corner turned red, so the crowd surrounded the car and started banging on the windows demanding autographs. No one rolled down the window, and thankfully when the light turned green, the car was able to go forward without hitting anyone.  

As the crowd was dispersing, I noticed that a lot of them were young men in their teens or 20s, and a lot of them were carrying the same pictures of the celebrity.  Plus they seemed to know each other well and were complaining about the stingy celebrity and comparing notes about who the "nice" celebrities are.  It makes me think that these guys are not typical fans, but professional autograph seekers who try to get celebrities' autographs and then turn out and sell them.  Their technique was very dangerous and someone could easily have gotten hurt.  

I had asked someone who the celebrity was when I saw the crowd chasing after the car.  It turned out that the celebrity was Sting.   It must have been pretty scary for him inside the car, with this mob of guys banging on the windows and screaming at him.
