Never 'really' met him. Somewhere in the mid 90's I went to a TV show because I knew he was going to be in it. The bit he was in it was awful (the show's host did a sh1tty job interviewing him).
I waited outside for him, but didn't have the courage to approach him. As a lot of people did in fact approach him and ask for autographs, I just stood there and watched from a small distance.
I take a great pride of not disturbing celebrities when I see one (not that it happens often, anyway), that ocasion was the first time I was tempted to try some kind of interaction with one.
I'm not sure I would want to meet him, now. How am I suppose to handle meeting someone you have an irrational passion for? This guy has been with me since I was 10. He has no idea the influence he's had on me for the last 30 years. I would not know what to say to him, and I surely would not want bother him just to tell him "I love your work", bla bla bla, he must have heard that millions of times before, and I would never be able to put in words the effect his music has in my life, so why bother trying?
Also, is it of any interest to a celebrity to hear a complete stranger babling nonsense in a starstruck state?
The only way I envision myself meeting him in a way that would not be a total embarassement for me was through another person, in a "normal people" event. Example:
A few years ago my sister's stepson went to a dinner at his friend's house. 6 people total in that dinner, in a regular home, normal people. Then somebody arrives a bit late to the dinner. It was George Michael. He joined the others at the table, normal people eating, drinking, and having a good time talking.
Everytime I remember that story I imagine it hapenning to me, just with MK instead of George Michael, and me instead of my sister's stepson. Wouldn't that be something?
