Bulletin (Sydney) 20 Oct. 24/2: George Frederick ’ll win it; there’s nothing else in it; / It’s a moral, I tell yer, ’e’ll smother ’em dead. // ‘An’ listen to me, sir, I’m no blanky geyser, / I tell yer I know what the beggar can do; / It’s no bloomin’ guiver; you scrape up a fiver / An’ plank it on now ’e’s at fifty to two.
