Oh the shark has pretty teeth, dear  And he shows them pearly white  Just a jack knife has MacHeath, dear  And he keeps it out of sight     When the shark bites with his teeth, dear  Scarlet billows start to spread  Fancy gloves though wears MacHeath, dear  So there's not a trace of red    On the sidewalk, Sunday morning  Lies a body oozing life  Someone's sneaking round the corner  Is the someone Mack the knife?    From a tug boat by the river  A cement bag's dropping down  The cement's just for the weight, dear  Bet you Mack is back in town    Louie Miller disappeared, dear  After drawing out his cash  And MacHeath spends like a sailor  Did our boy do something rash?    Sukey Tawdry, Jenny Diver  Polly Peachum, Lucy Brown  Oh the line forms on the right, dear  Now that Mack is back in town
