My Fair Lady is, and shall remain, one of the greatest musical comedies ever with a luscious score, romance, wit, sparkling production numbers and even a touch of social philosophy. Hard to believe it’s almost 52 years old and the play upon which it’s based (Shaw’s Pygmalion) is approaching 100! This touring production is from the award-winning Royal National Theatre of Great Britain revival, as transferred to London’s West End by producer Cameron Macintosh. So what if you never heard of its stars? They are gods in Britain, the show is divine, and Mr. Macintosh never puts out shoddy product. My Fair Lady plays only through Feb. 3; Cadillac Palace Theatre; 312-902-1400; $25-$75. Photo of Liza O’Hare and Christopher Cazenove by Joan Marcus
