Delightful, Oscar-winning musical based on George Bernard Shaw 's play Pygmalion, starring Audrey Hepburn and Rex Harrison, showing in a night of BBC Voices programmes on regional accents and dialects. Henry Higgins, a phonetics professor, bets his friend Colonel Pickering that he can coach a cockney flower girl to pass as a lady at any social function. The girl, Eliza Doolittle , initially scorns the idea, but later turns up at Higgins's house seeking tuition.
