It's been a busy week over at Wicked , as Broadway.com Oz Blogger Andy Karl will tell you. Reigning witch Dee Roscioli officially passed her pointed hat over to newly minted Green Girl Mandy Gonzalez, who's now defying gravity nightly. The Gershwin Theatre also got a visit from a group of high schoolers, who then got a surprise visit from Andy and his handy cam. But, as you know by now, the Oz Blog is all about it's totally random musical numbers, and this week we've got two : Tony Award winner Rondi Reed's "Livin' the Dream" and a new a capella ditty by Karl himself. (Note: Stephen Schwartz has not approved either of these numbers for Wicked playlisting...but we kind of like 'em.) Watch the video to get the seven week itch with the one and only Andy Karl!
