When I lived in South London I used to bump into Jools Hooland and his little boy at our local cafe - Jools is a really friendly bloke - no ego - genuine.
i have also met Peter O'Toole , Eddie Izzard, Clive Barker, Alun Armstrong, Elizabeth Berkley ( Show Girls ), Charlton Heston, Rob Lowe - all of whom wre friendly and were chatty.
However - when drinking at a pub in London called the Plough some years ago, I was at the bar with a friend , and there drinking were Gillian Taylforth, Danniella Westbrook and Jeff Knight. They behaved liked they were the bees knees - Knight was doing his hardman bit all night long to any bloke going to the bar - what a w*nker.
