I've been looking for information about whoever composed the music for Red Baron II. Wikipedia and Mobygames say nothing about it. However, one website (http://www.answers.com/topic/red-baron-3d) said that the music was by a Chuck Barth. A Google search for "Chuck Barth music" then turned up this guy: http://www.linkedin.com/pub/chuck-barth/7/508/561
And he lists Red Baron in his credits. So at least I now know who composed the music. But I wonder why he is a non-person on Mobygames and the Wikipedia article about Red Baron II.

I love the music in RB3D. I always thought it was a collection old military marching songs, nothing written by anyone alive when Red Baron was in production. I always wondered where the band came from that played the music, I have never seen any credits for them.

I don't remember it well enough to say for sure, but it might have been done with software and expensive samples, like Jeremy Soule's music for Wings of Prey. It can be very hard to tell high-quality samples from an actual orchestra.

It's somewhat similar to the (marching) theme song from the movie The Great Escape
