One more comment on this... I would just recommend doing away with all of these footnotes except for the first one, and replacing the battle links with a link to that article for "Marathon to Waterloo".  This is basically a trivia section, and it's open to interpretation as I think these are missing the point of the song.  Things like the frog chorus highlight the breadth of his classical training versus the shallowness of the martial trivia he possesses; they don't need to be impressive in and of themselves.
