Oh the shark has pretty teeth dear And he shows them pearly white Just a jack-knife has Mac-heath, 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 Mac-heath, dear So there's not a trace, not a trace of red On the sidewalk on a Sunday morning Lies a body oozing life Someone's sneaking 'round that corner Tell me could it be, could it be Mack the Knife On a tugboat down by the river, don't you know A cement bag's dropping down The cement's just for the weight, dear Bet you that cat called Mack-heath, oh Mack-heath, he's back in town Oh Mack-heath's back in town He's back, he's back, he's back, he's back He's back, he's back, he's back, he's back, he's back, he's back in town Mack-heath's back in town
