Kristin Chenoweth

A diminutive blond with a piercing, helium-tinged belt and a comic manner that harks back to great funny women of old, Kristin Chenoweth is the most distinctive musical-theater star to emerge in decades. She's also an Emmy-winning TV actor, an accomplished coloratura soprano and a first-rate concert performer; tonight she drops by the American Songbook series. (Good luck scoring seats.)
