When the talk is about international show business, the name of Margaret Kelly does not immediately leap to mind... yet few have dazzled more audiences. Miss Kelly, born in Dublin, abandoned by her parents, adopted by a Liverpool family, grew up to be Miss Bluebell, the iron hand behind the velvet gowns of thousands of dancers and statuesque showgirls who have been widening eyes since 1934. The Bluebell Girls dance their way through the Lido lights in Paris, the Stardust Show in Las Vegas, the International Casino in Nairobi; in Buenos Aires and Madrid. So what sort of person is this Miss Kelly, who sets them dancing and who, after 35 years, still commands their routines? And what are the Bluebell Girls like when they are dressed? To find out, Alan Whicker went to Paris - willingly!
