Lali, thanks, it's good to know you liked it too. I can't compare the play and musical yet, but if you like theater, you might want to give the stage play a try. There's a DVD with the origin Broadway cast that's very good. I'm not actually a huge fan of musicals, but this one I do like a lot.
And the Agony reprise is a treat - the Princes are now singing a similar song, but about Snow White and Sleeping Beauty, and ends "oh, well.... back to my wife"
