Sweeney Todd: [Holding up razor.] At last, my arm is complete again!
Sweeney Todd: No! Not Barker. That man is dead. It's Todd, now. Sweeney Todd. And he will have his revenge.
Sweeney Todd: You have a room over the shop, don't you? If times are so hard, why don't you rent it out?
Mrs. Lovett: People think it's haunted.
Sweeney Todd: Haunted?
Mrs. Lovett: Yeah. And who's to say they're wrong? You see, years ago, something happened up there. Something not very nice.
Judge Turpin: Oh yes... Such practices. The Geishas of Japan, the concubines of Siam, the catamites of Greece, the harlots of India. I have them all here, drawings of them. Everything you've ever dreamed of doing with a woman. Would you like to see?
Anthony Hope: I think there's been some mistake.
Judge Turpin: I think not. You gandered at my ward, Johanna. You gandered at her. YES, sir, you gandered!
Anthony Hope: I meant no harm.
Judge Turpin: Your meaning is immaterial. Mark me! If I see your face again on this street, you'll rue the day you were born.
Mrs. Lovett: Barker, his name was. Benjamin Barker.
Sweeney Todd: What was his crime?
Mrs. Lovett: Foolishness.
Mrs. Lovett: You've got to put the past behind you now. What's dead is dead, and life is for the alive my dear. We could have a life, us two. Maybe not like I dreamed, maybe not like you remember, but we could get by.
Mrs. Lovett: That's all very well, but what are we going to do about him? Hello? Can you hear me? Oh, you great useless thing.
Anthony Hope: Is everything all right Mister Todd?
Sweeney Todd: My mind is far from easy, in these once familiar streets I feel shadows... Everywhere.
Anthony Hope: Shadows?
Sweeney Todd: Ghosts.
Mrs. Lovett: You're barking mad! Killing a man what done ya no harm!
Sweeney Todd: He recognised me from the old days. Tried to blackmail me. Half me earnings.
Mrs. Lovett: Oh, well that's a different matter then. For a moment there I thought you lost your marbles. Ugh! All that blood. Poor bugger. Oh well!
Answer: From what I heard, the chorus songs (known as "The Ballad of Sweeney Todd") were cut due to time and inability to make the chorus work on-screen. Actors were set up to play "ghost narrators" at first, so that indicates that the filmmakers did want to include the songs. They were just not able to find a way to make them work satisfactorily for them. Also, I think (can't verify) I also heard that Stephen Sondheim, the show's original creator and composer/lyricist, agreed that these cuts needed to be made for the film to work.
