Ostrum was tutored on-set for three hours a day, though sometimes only for 30–60 minutes at a time.[6] Though in his audition he had been assured that his singing would probably be cut and dubbed, it was Ostrum's own singing voice that made it to the screen—albeit significantly cut.[1] In a 2011 interview, Ostrum told the story of how director Mel Stuart gave him a clapperboard from the film, and later on asked him how he got it because he had forgotten that he had done so; it is Ostrum's only souvenir from the set.[9]
