My Fair Lady is a musical based upon George Bernard Shaw's Pygmalion and with book and lyrics by Alan Jay Lerner and music by Frederick Loewe. The story concerns Eliza Doolittle, a Cockney flower girl who takes speech lessons from professor Henry Higgins so that she can pass as a lady. Higgins takes credit for Eliza's success, but she realizes that she can now be independent and does not need him.

The musical's 1956 Broadway production was a smash hit, setting a new record for the longest run of any major musical theatre production in history. It was followed by a hit London production, a popular film version, and numerous revivals. It has been called "the perfect musical."
