One Tuesday evening back in 1995 whilst visiting London with work I was sat in a empty bar minding my own and in glided Michael Jackson with two huge bodyguards. He ordered a shandy and was accompanied by a woman (his guitarist apparently). We didn't talk but I was earwigging their conversation and overheard him talking about his upcoming HIStory gigs at Wembley scheduled for that weekend. They were talking about the set list etc.
The things that struck me most about him were how normal he seemed, how loud his laugh was, how gracefully he moved, and that he drank! (albeit shandy). He also tipped the girl behind the bar £50. A mad experience, and for star power it takes some beating.
