My Fair Lady is a  classic musical with book and lyrics by Alan Jay Lerner and music by  Frederick Loewe, based on George Bernard Shaw's play Pygmalion. It  tells the story of linguistics professor Henry Higgins' bet that he can  transform Cockney flower girl Eliza Doolittle into a refined lady,  exploring themes of class and identity through iconic songs like "I  Could Have Danced All Night" and "The Rain in Spain". The  original 1956 Broadway production was a massive success, winning  multiple Tony Awards, and was later adapted into a famous film.
