The few shots of her when she was in the stadium seemed to show her none too pleased with what was going on. Fortunately her only role there was to make a short statement declaring the games open. She became the first head of state to open the games more than once. IIRC she wore a light pink dress for opening the games in Montreal in 1976 and beamed when her daughter Princess Anne marched past as a member of British team.
Why didn’t she also open the Sydney Games?
