Ive found the Lyrics.

Come into my parlour said the Spider to the Fly.
Come into my Barber shop said Todd..... unto Toby.
For a roughness I detect about the throut I fear?
Me thinks it would be better.............When....Cut from ear to ear.

Sweeny Todd is my Name cutting throats is my.............Game.

Upon the secret pedle my foot I do depress.
Flung back into the dark abyss.....unto eternal rest.
For my mistress Lovett meat for her pies does need.
A busy shop aboiling pot.............And customers to feed.

Sweeny Todd is my name cutting throats is my..............game.
