George looks gorgeous in pinstripes, pocket handkerchief and cravat, swaggering out of the Band On The Wall in a burgundy Homberg hat, singing "Ratatatay, ratatatay!" George after-hours and the worse for whisky when somebody shouts "Hey, you!" in a pitch-black Manchester backstreet ... well, what's a poor singer to do but sing "Ratatatay, ratatatay"? Two men flashing a knife blade, saying "give us your notes and your watch" - Singing the backstreet stand-off to the rhythm of the fear and the scotch. George, not wanting to feel the knife, cornered and speeding and scared ... from the back of his mind comes 'Ursonate', Sound and fury and words. He sings: "Ratatatay, ratatatay!" So the robbers are stuck to the spot now, watching George as he sings for his life. Menace turns to panic and they turn and run and the song waves goodbye to the knife - singing "Ratatatay, ratatatay!"
