Hi, Queen Silvia was amazing in the pictures i have seen, she was (and is a spectacularly beautiful woman. As to ABBA singing and dressing up in the old fashioned costumes, I read that they were extremely honoured to do so and that it was the very first time a rock or pop act had ever been asked to perform for a Swedish monarch. Dancing Queen had been written and recorded about six months before. Bjorn said in an interview that `if you have a song called Dancing Queen you sing it for your future Queen on the eve of her wedding`. Queen Silvia was said to adore the song and regarded it as a special present for her. Ive said it before and i will say it again ABBA were (and still are) the very best.
