[Sung by a large pair of blood-red lips]


Oh, Ben Barker was fine, his life seemed just divine
With his Lucy hand in hand
But Judge Turpin was there, he liked to sneak and stare
Like some pervert Invisible Man
Then something went wrong
And you know, before long,
Poor old Ben found himself in a jam:
But he came back to that place,
Pale makeup on his face,
And this is how the story ran:

Violence Fiction,
Tragic story
Sweeney’s vengeance
Will be quite gory
See Mrs. Lovett’s
Failed seduction
As Sweeney heads for
Self-destruction
Whoa-o-o-oooaoh...
At the late night

I knew Senor Pirelli’s
Elixir was smelly
But he said it would cure all of your ills
And I really got hot
When I saw how he got
His comeuppance from a razor that kills!
Beadle Bamford asked Todd
For a pomade
And killing him gave Sweeney joy,
Then he offed his bride
Mrs. Lovett got fried
And soon the only one left was the boy,

It was:

Violence Fiction,
Tragic story
Sweeney’s vengeance
Was quite gory
Poor Mrs. Lovett
Could never sway him
And that’s why Toby
Had to slay him
Whoa-o-o-oooaoh...
