Which witch is wicked?

We are staying at the Marriott on the Thames adjacent to the Westminster Bridge.  We can see the river from our room. Great spot. A few steps and we are on the walkway that follows the waterway.  Before the daily crowds arrive it's a great spot to run.  That's how I started my day.  No better way to see this city. On a cool, freshly rained on morning ended up at Trafalgar Square for a venti and watching the London work day come alive out the window.  

We did a cruise on the river after breakfast then back on the Big Bus "red" tour with a live narrator. The day seemed to slip by too fast.  Made it back in time to get changed, go to dinner at a cool little Asian noodle restuarant in the same building as the Hotel then off to our second show: Wicked!  A spectacular musical that's amazing in every way.  Special effects, music with a live orchestra, great acting....and for a guy that didn't know the story, a refreshing spin on the Wizard of OZ.  Still trying to figure out what they were thinking when they built a 1300 person theatre with one itsy bitsey bathroom and a narrow window of opportunity to take care of business.  Long lines and chaos ensue.
