Molly's wish to see the musical "Wicked" (prequel to the Wizard of Oz) on Broadway was fulfilled Wednesday evening. She had center aisle seats close to the stage from which to take in the music and drama. Afterward, a backstage tour led by actor/musician Anthony Galde included meeting lead actor/musicians Ben Vereen (the Wonderful Wizard of Oz) and Shoshana Bean (Elphaba, the "wicked" witch). Highly acclaimed, "Wicked" has been playing to a sold-out Gershwin Theatre since opening over two years ago. Now with two touring companies, the musical's influence is spreading at a rate comparable to "The Phantom of the Opera" and "Les Miserables." Its songs were a major feature in high school "show choir" competitions last spring. Wonder what it's about?
