Mack, the Knife - Parkinson's Edition 

Oh the shark, babe, has such teeth, dear
And it shows them pearly white
Just a jackknife has old MacHeath, babe
And he keeps it out of sight
You know when that shark bites with his teeth, babe
Scarlet billows start to spread
Fancy gloves though wears old MacHeath, babe
So there's never, never a trace of red
