Sandie Shaw wins the Eurovision Song Contest for this country; Twiggy becomes the most talked-about export to America we have had in years; Johnny Speight , the man behind the cockney comedy show Till Death Us Do Part, causes an uproar and is asked to write a new series for a vast sum of money: and designers like Alan Aldridge with their shoulder-length hair and Cockney twang are invited for royal lunches. All four of them are in this week's programme. It's not just talent and a lucky break. It seems to be a positive advantage these days not only to be successful but to be working* class with it. Perhaps it helps all of us to believe we are becoming a classless society.
