From what i remember they were pretty much raves, weren't they?
I love this show and think it's worth every penny of the £75 top price. It's not to everyone's taste, but i think it's a brilliantly crafted show. My 76 year old, strict catholic mother thought it was the funniest show she has seen.
There are a few very cheap seats (£13 plus ATG's outrageous £3.65 booking fee) in the back of the stalls and circle (and more seats at that price in the upper circle, but I don't do the upper circle in the Palace). The £13 seats in the stalls and circle will not hang around for long, but as of ten minutes ago they still seem to be available for nearly all performances. I just bought one.
ATG's website is being particularly annoying today. It took three attempts to buy a ticket and check out; at the first two, when I tried to put a ticket in the basket I just got an endless spiral of death. So that was fun.
That reminds me of the current tour of Wicked stopping at Zurich beforehand. I'd say it's economically best to have the tour production there to save on building an extra set and rehearsing a whole new cast. And it's a very well-known show so I wouldn't be surprised if they threw in a couple more European dates such as Paris, Madrid, Zurich etc.
