Johnny Depp struggled with one song on the SWEENEY TODD soundtrack - because he had to hold a note he feared he'd never be able to. When the movie star signed up to play the demon barber of Fleet Street in Tim Burton's dark musical he insisted he'd stay true to Todd creator Stephen Sondheim's songs - even if they proved difficult to nail, like Johanna. He tells Rolling Stone magazine, "It's such an emotional song and as far as I was concerned, when Stephen Sondheim writes the note and it has to be held for this many beats, you do it. "Don't be a pussy, you f**kin' hold that note. You can't cheat. You can't whisper... You just gotta belt it out. "I really beat myself up, making sure I could hold those notes. In Johanna, some are, like, 12 beats. That was a bugger. At one point, I was close to passing out - I got dizzy and saw black."
