Can Frankie finally do it? Can Aiden O’Brien finally do it? Can Sheikh Mohammed finally do it? Yes, it’s Melbourne Cup time, when the land down under goes over the top for a horse race and when the world’s racing elite ply their annual quest, before going home wondering what the hell happened, again. This is that peculiar Australian festival of wanton abandon to the punt and the plonk; a hangover from another era, that gives annual licence to a national hangover. No other national event can so conjure Australia’s historic and reckless will to party.
