Does anybody else only want to see the "Doll on a Music Box" part?
I bought the DVD (this was a little bit before YouTube, if I remember correctly) simply for that particular scene. It's not that I don't care for the rest of Chitty Chitty Bang Bang, but the "Doll on a Music Box" segment always (besides of course, the freaky Child Catcherš) stood out as the highlight.
I don't know if it's because I was always amazed by Sally Ann Howes because she's so beautiful and has such a sweet, angelic singing voice. Maybe I'm turned on (no pun intended) by her cute dirndl outfit and the nice little touch of her standing with one of her heels up.
Also and more importantly, the fantastic choreography while portraying a mechanical object. You have to imagine how complex and intricate (apparently, Sally Ann Howes did that sequence in a single take) it must be to quickly contract and relax your muscles enough to cause a jerk your body. In essence, Sally Ann was the godmother of "popping":
