Tom was talking to me about Sportfreunde Stiller the other day.. they have a new(er) album out called La Bum, but it doesn't have this song out on it. I guess that makes sense since this was a hit when Germany was hosting the World Cup in 2006. '54, '74, and '90 are the years when Germany has won it. They were hoping for 2006, but unfortunately that didn't work out.
It's a fun song, and if you can imagine masses of rowdy drunk fans singing this around the Brandenburg Gate, that's pretty much what it was like in Germany during the World Cup. I wasn't there... but that's what they told me.
On a more cultural/historical analytic level, many people said it was one of the first times they felt that Germany emerged from the shadow of WWII and National Socialism to celebrate their patriotism without feeling like the next step would be a nationalist putsch. So I suppose it's progress... resulting from decades of national therapy sessions. For more, you might want to check out the movie Deutschland. Ein Sommermärchen.
I think it's actually good to be critical of expressions of nationalist fervor. It's part of what makes me like Germany, that unwillingness to celebrate King & Country. America is completely the opposite, except for pinko commies like me, I suppose.
Enjoy the song. I hear it's been amended already for the next Eurocup or World Cup.
