Have you seen Wicked? If not, you're totally missing out. My lovely friend Stacy invited me to see a production of it in Costa Mesa in 2006. In the car on the way there, she played the soundtrack and told me bits and pieces of the story. I LOVED the production and immediately went home and devoured the book and sequel and highly recommend you do the same. Since then, I've seen Wicked twice more, both at the Pantages Theatre in Los Angeles. I have a shirt and the Grimmerie and lots of programs.
My absolute favorite cast is the original Broadway one that I first saw - with Kristen Chenoweth and Idina Menzel. Kristen is the funniest actress ever and you're probably familiar with her even if you think you aren't. Ever see the show Pushing Daisies? She played Olive.
As for Idina, she's gorgeous, even when she's green. And her voice.. it gives me shivers. Every song she sings - and she has solo recordings that are amazing - is beautiful. Also, she's married to Taye Diggs - which makes her sexy by proxy.
This video takes place at the height of the action in the play, the turning point for both main characters. The song is lovely by itself, but it takes on so much more meaning once you know the turmoil they're going through at that moment. So go see it - it's playing somewhere near you! Second best: buy the soundtrack and play all the songs - they're funny and moving even if you don't know the story!
