Not While I'm Around is sung by Toby to Mrs. Lovett. Toby sings to Mrs. Lovett of "certain dangers", which is actually Todd because Toby has suspicions of him.
Lyrics
Nothing's gonna harm you, not while I'm around. Nothing's gonna harm you, no sir, not while I'm around.
Demons are prowling everywhere, nowadays, I'll send 'em howling, I don't care, I got ways.
No one's gonna hurt you, No one's gonna dare. Others can desert you, Not to worry, whistle, I'll be there.
Demons'll charm you with a smile, for a while, But in time... Nothing can harm you Not while I'm around...
(Dialogue)
Not to worry, not to worry I may not be smart but I ain't dumb I can do it, put me to it Show me something I can overcome Not to worry, Ma'am
Being close and being clever Ain't like being true I don't need to, I would never hide a thing from you, Like some...
No one's gonna hurt you, no one's gonna dare Others can desert you, Not to worry, whistle, I'll be there! Demons'll charm you with a smile, for a while But in time... Nothing can harm you Not while I'm around...
