Beyonce @ NATO
This is an off-topic and irrelevant anecdote so feel free to downvote or delete. Oh, and I can't find supporting links or even remember the year so feel free to disbelieve.
The Edinburgh International Conference Centre hosted NATO ambassadors or foreign ministers discussing the occupation of Afghanistan at the same time as it hosted a music awards do.
This led to a lot of peace protesters and music fans out front trying to get in, and wads of police and security easily stopping them.
I wanted to get inside to protest the Afghan war but I knew the area so I walked across the Western Approach Road into the parking area. Apparently too dangerous for any security. There was still no way into the building, the car park doors needed security keys, so I was about to turn back when one door opened.
Beyonce stepped out in a sparkly green evening dress. I hadn't seen or even heard of Beyonce so my first thought was, "That is a strange costume for a NATO ambassador."
I moved to get inside the door before she closed it, nearly bumping into her, and immediately two huge black guys in tuxedos got between me and her and were obviously about to deck me. I gestured past her to the door, and they realised I wasn't after her and let me in, while shielding her from me.
It was only when I saw the local STV news later that I learned who she was. I still get to the NATO ambassadors but I got closer than anyone else, and I learned they were less protected than the music folk, several of whom I passed in the corridors. Again, I don't know who any of them were so any interest you may have had has been misplaced.
[I have a similarly boring, if shorter, anecdote about Alexander Usminov and Naomi Campbell if anyone requests it]
