I love this movie, too! It's funny, but I remember one of the critics' loudest complaints about the lyrics in the songs was the bad grammar the songs used. Obviously, they missed the opening narration in which it's made clear that the newsies were "poor orphans and runaways". They aren't going to talk OR sing like Harvard graduates. The music is just great, Alan Menken is a talented composer! I think in the right hands, and with a few additional songs (a duet for Jack and Sarah's characters set to the music of the rooftop scene, for example), this would translate very well to the stage.
