As London gears up for the Olympics, I hope it'll be a chance to celebrate some of London's characters other than the (by then ex) Mayor Boris Johnson, who is listed in Wikipedia, harshly but correctly, as having 'no courtesy, title or style'. My nomination is the Singing Cabbie, who doubles his taxi-driving with his other job as a Frank Sinatra tribute act. 'Wanna hear some?' he asked as we travelled down Bloomsbury Street. Whereupon he closed the windows, locked the doors, put on a big band backing track and sang 'Ain't that a kick in the head'. Give the man a medal.
