What song from Sweeney Todd should i sing for a project?

ok, in my chorus class, there's a project where we had 2 write 10 intresting fax bout ourselves & the teacher compared it w/ a musician & she assigned a musician that she thinks was like tht 1 person. & got the guy who did the music 4 Sweeney Todd. & i'm going to sing a song from the film Sweeney Todd. I need something that isn't slow, like Epiphany.
