Tucker, it's something I had marked in my Oxford Dictionary of Quotes. The author, Arthur O'Shaughnessy lived from 1844-1881. Up to the last line it gives the credit to his "Ode". The last line does not make reference to what it is from; I would assume it is from the same piece. I would asusme, also, that is where we got the expression about the movers and shakers of the world. If it's not in a tune, or even if it is, write yer own, eh?
