What's the name of the song in Fred Bonaparte's level?
Solution 1:
The name of the song is "Napoleon's Final Conflict Revisited."
It has taken parts from Tchaikovsky's 1812 Overture hence the classical composition, so in fact has been both composed for this game a bit as well as being part of a previous work.
