Diamond Jubilee: Queen won't let health and safety mess up hair majesty "I really think it is ridiculous that you above all others do not wear a crash helmet," he said to the Queen while hacking in The Home Park, Windsor. "I never have," she replied, "and you don't have to have your hair done like I do."" Bedell Smith, who has also written a biography on Diana, Princess of Wales, added: "It was an expression less of vanity than the practical need to be ready for her appointments." In her 1000 word commentary for a special Diamond Jubilee edition of the magazine, Beddell Smith also disclosed that the "otherwise prim and proper Queen can stand in the corner of the covering shed at Sandringham, calmly watching the raw and violent mating of her thoroughbreds." She wrote that Sir Michael Oswald, her long-time stud manager, told her: "Very matter of fact. She knows how it works. The Queen, who "loves to sing," can also be "equally absorbed" by what her former private secretary Sir Philip Moore once called her "tiara time" before formal banquets. She wrote: "Using a kit with tools, she decorates certain diamond tiaras by hooking on pearls, rubies, sapphires, emeralds - a pastime she thorough enjoys, according to former Crown jeweller David Thomas." A spokesman for Buckingham Palace declined to comment.
