Many years ago, working in showbiz, I met lots of famous people. From that time, the nicest person I spoke with was probably Johnny Walker (legendary DJ). He was natural, friendly and a pleasure to interview at Radio 1. The nastiest was Leslie Joseph (Birds of a Feather), who came across as self-obsessed with a vastly over inflated idea of her own minimal talent.
Today, living on the IOW, I sometimes bump into David Icke, who contrary to what many may think is a nice bloke with some interesting thoughts. I also bump into Melvin Hayes (It Ain't Half Hot Mum) who is shy of celebrity, and just wants to be given space to live his life. Which is fair enough.
