Yeah, she does have a certain cuteness about her. When I saw them live a few months ago she was having bra strap issues, and there was something very sexy about her pulling the strap back into place between strums. Heh.
I actually had no idea she was singing half of each verse on that song until I saw the above show. Her voice on that song is much deeper than the rest of what you hear from her, as well as quite a lot deeper than her speaking voice.
