if it was a horrible color, he'd have still had to have worn it. >> reporter: so you just do as you're told, says william. the queen can reduce grown men to blithering idiots, william admits, even within the family it happens. but on their guest list she was cool. i was given this official list, 777 names and not one person i knew, so he called grandmama, who told him to rip it up. she said, start with your friends, and go from there. by the way, driving his bride in his dad's favorite car, nervous william, a military helicopter pilot left the emergency brake on. the cheering drowned out the grinding. now the queen has given her life to royal duty. "we do hint at taking some things off her," says william, "but she won't have any of it." and william's in no hurry to take over.
