I'm also a fan of that Sochi Gala performance! This might sound weird, but when I see that I think of Tolstoy's "War and Peace".:shocked: There's this scene where Natasha does a Russian folk dance after a wolf hunting trip in "uncle's cabin/lodge" (haven't read it in english). The narrator (I like to think Tolstoy himself) is fascinated at how well she performs and how truly she understands the "soul of Russia". This is one of my favorite bits of that great novel.
By the way, Countess Natasha Rostova, one of the main characters, is an emotional, petite teenage girl usually full of positive energy. "Constantly smiling and laughing" as Andrei observes the first time he sees her. She's also very musical, a great dancer and she is from Moscow.
Now you probably understand why it's difficult for me to seperate the two performances
