Do Re Mi
From the movie Summer Holiday (1963). Do Re Mi is a trio of English lasses on their way to their first singing gig in Athens, attempting to cross the continent in a broken down jalopy straight out of Archie comics. Naturally, there's one of each hair color: brown-haired Angie (Pamela Hart), black-haired Sandy (Una Stubbs), and blond haired Mimsie (Jacqueline Daryl).
