Audiotrack,
You're absolutely right, the question was "Is there an automatic chord analysis in Band in a Box?", and your answer with the reference to the ACW is exactly right :-).
In fact the ACW is rather unsuitable for this kind of music, I tried it with the song in question and the ACW result has indeed hardly anything to do with the actual chords. That's why I referred to the google search.
However, the ACW actually works surprisingly well at times with music where chords can be heard clearly and distinctly.
