Two things.
After Finlandia they played a Violin Concerto by Sibelius, and for it, a Bulgarian violinist, Bella Hristova, joined the kru. She was really quite incredible, and after the show, during the booming applause, she received a huge bouquet of flowers. Yay for that. The Finnish conductor, Jari Hämäläinen, however, instead of flowers got a large bottle of "something". They really know how to make their Finnish guests happy, it seems. :)
After the violin concerto, there was another interesting thing. A group of 10 or so 75+ years old grannies apparently figured that normal applause weren't enough. Instead they started banging the floor with their feet, making the entire floor shake, and shouted in unison: "UH-UH-UH-UH!" My guess is that they (or everyone around them for the past 50+ years) were rugby fans.
