Have a good time, all the time!
But the lyrics are about war and death but belittle the horrors of it and make it sound like fun.
Yes I Agree, It's about the Excitement & Adventure of War. It was fun for von Richthofen and other people like Rommel and Patton loved war they enjoyed it very much. 9 out of 10 maiden songs about war have a very anti-war message (2 minutes to midnight, The Trooper, The Legacy) but it isn't like they haven't portrayed War & Battle this way before (Die With Your Boots On, Flash of the Blade, Aces High)
