Is it embarrassing to admit on this forum that one has seen WICKED six times? Twice during previews because, well as far as musicals go, I tend to see everything twice, then because I just had to see Taye Diggs and Idina Menzel together onstage after all those years, then again because I had to see if Randy Harrison (of QUEER AS FOLK) could really hold his own (no pun intended) on a Broadway stage, then again to see a neighbor go on, then again because it was Idina Menzel's final weekend. (I ended up seeing her real final performance totally by accident - no pun intended there, either.)
The only show I've seen more times was BIG, which I saw seven times, because for all its flaws, BIG it was a really reliable pick-me-up while my b.f. was out of town for several months, and it was only three blocks away. (As my shrink friend says: Hmm, BIG and WICKED, someone's just trying to run away from the real world.)
