The scene was inspired by the painting of the revue at the Arc de Triomphe du Carrousel by Bellange. Not only could I have the Band, but also include some of the French Top Brass.
Playing a variety of instruments including the bassoon, hautbois, cymbals, jingling johnny, flute, serpent and (that most martial of instruments), the triangle, they provided the accompaniment for the great parades of the First Empire.
Sorry Richard, I'll let you in after closing, but I'm just too tired to write anything right now. I'll catch you up in the comments later. :)
