Yes, there are too many musical revivals on Broadway, and yes, there are too many La Cage aux Folles revivals (the latest, perfectly decent one was just six years ago). But none of them had Douglas Hodge, the British Shakespearean actor who plays the flamboyant, cross-dressing half of the central gay couple with such intensity, humor and heart that he raises the show to a new level. Jerry Herman's score sounds as good as ever, and Terry Johnson's lean, grounded production (imported from London) makes you appreciate Harvey Fierstein's well-constructed book. Isn't that pretty close to the definition of a perfect revival?
