There's a lot of Finns who feel that Finlandia should be our national anthem. We don't actually have one by constitution, but we've been using Maamme for the purpose. The only good thing (in my opinion) about Maamme is that it's almost impossible to mangle it. You just need to make a lot of noise when you sing it.
Yup. We even call it our national anthem. It's just not one by law.However, isn't it used whenever a "National Anthem" is needed or called for by decorum?
I've always thought the US should have picked a song that was easier to sing, like "America the Beautiful" or "Yankee Doodle".
