Platinum certification means the Decca Broadway recording has sold at least one million copies. The disc — featuring such tunes as "Defying Gravity," "Popular" and "The Wizard and I" — is also currently #1 on Billboard's Top Cast Album Chart.

It's been a good few weeks for the hit musical at the Gershwin Theatre. It was also recently announced that the musical broke the all-time Broadway box-office record, bringing in $1,715,155 for the week ending Nov. 26.

With a score by Stephen Schwartz and a book by Winnie Holzman, Wicked began previews on Broadway Oct. 8, 2003, after a summer tryout at San Francisco's Curran Theatre.

Based on Gregory Maguire's novel, which turned every Oz myth inside out, Wicked explores the early life of the witches of Oz: Glinda and Elphaba. The two main characters meet at Shiz, a school where both hope to take up sorcery. Glinda is madly popular and Elphaba is, well, green. By a misunderstanding, they wind up roommates and, after an initial period of mutual loathing, begin to learn something about each other. Their life paths continue to intersect through a shared love, entry into the Emerald City and interaction with the Wizard himself. Eventually, their choices and convictions take them on widely different paths.
