Oh let's see...I can remember a few.
I saw Beyonce perform in front of the castle a few years ago singing "Silent Night" for the Xmas special. I watched her perform it like 6 or 7 times before I moved on. The weather was iffy the whole time and the camera crew kept yelling at people to take off their rain gear. Funny, hearing her singing before and after around the park I know she sang it at least a dozen times. I was very impressed - she was quite a trooper. She had on a white sleeveless dress, it was pretty chilly out, plus the rain kept coming - and she never stopped, even when getting wet, until the director told her to go back and start again or to go backstage and wait. Didn't complain, smiled the whole time, waved to little kids in between. I was very close at one point, and then ended up meandering away (as cool as it was, how long can you sit and watch that? LOL). Funny thing was, the sun came out a little while later, and that along with some tinkering with the video made it look like a lovely bright day when it was edited.
I saw Cameron Matheson at the height of his Dancing mania, coming off of Star Tours 2. There was a camera crew waiting for someone right outside the simulator door. I kind of lingered at the bottom of the platform to see who it was. He came out with his son, and they asked them how they liked the ride. I totally had my camera in my hand and could have taken a picture (the ladies at the office killed me for not doing it!) but I felt weird taking a pic of him with his kid. In retrospect, they were being filmed anyway (though I never found out for what - some promo I assume but I never saw it) it wouldn't have been awful to do so, but I like to be respectful. And yeah, he is even hotter in person, LOL.
I know there are a few more...but those are the most recent I recall with clarity.
