In a word - AMAZING. Loved it. Loved it. I need to buy that soundtrack now. Also, the "Ozmopolitan" cocktails they have for sale at the Regent Theatre for $10 are quite tasty (and you get to keep the glowing glass!)
And because it was clearly the best song of the show, here is Broadway and West End's "Elphaba" Idina Menzel singing "Defying Gravity" at the Tony Awards several years ago.
