John Simon reviews: No matter how many times you've seen ``Gypsy,'' you arguably haven't experienced it as fully as you may now on Broadway at the St. James Theatre. I think I have caught them all, starting with the legendary Ethel Merman in the premiere, but it is this one that has definitive written all over it.

In Patti LuPone's Mama Rose, Boyd Gaines's Herbie and Laura Benanti's Louise, the musical has that radiant nucleus around which everything else coalesces into a parade of delights. This is the ``nec plus ultra'' of ``Gypsy'' productions, than which I can imagine none greater.

You surely know this revered musical tells the fact-based tale of Rose, the stage mother from hell, and daughters June and Louise, whom she prodded and propelled into stardom as June Havoc and Gypsy Rose Lee.
