Stuart,
A little story about MJ and all true - for I was there and part of it.
When he came to London, he stayed at The Mayfair Hotel and I was the Director of Engineering. He took the 2 bedroom Penthouse Suite and I was asked to remove the bed from the second room and put in a wooden floor. I naturally presumed that he wanted to hone his dancing skills, but I was wrong. His remote controlled toy cars would not work on the carpet.
Anyways, his personal minder was called Bill Beaumont and was a retired Los Angeles policeman. He gave me 2 tickets to his Wembley concert, but unfortunately, I could not go on that night, so I gave the tickets away. I was asked to go the second night and ended up on the sound stage.
Still, to this day, the most professional concert I have ever seen and MJ was amazing.
