She did versions of Takin' Back My Love and Love/Sex/Magic which was a nice addition. Also she was doin loads of energetic dancing etc and sang live. Soon after Ciara this Big Apple Circus Group came on, who were pretty impressive!

(or should I say down?!)

It was a really good show, she did loads of the old songs as well.. The whole concert seemed to be quite long (even though the time goes fast!) so you get your money's worth.
She didn't perform Gimme More or Break The Ice, but they were played during an interlude bit where she got changed. I was quite surprised that ther were alot of songs from Blackout, I thought maybe more from Circus bearing in mind it was the Circus tour. I remember Ooh Ooh Baby, Get Naked, Hot As Ice, Piece of Me, Radar and Freakshow..there may have been more.
No Kill The Lights or Mannequin, which was a little disappointing..but she made up for this by doing some of the old classics..Toxic was a class performance and the crowd loved it.
The finale was Womanizer and was a pretty good ending, all confetti shoots into the crowd..

The most impressive thing about this concert was the staging and dancers and props and special effects that are used. You can't help but be in awe of all the people who must work behind the scenes getting the stageing, lighting prepared. At one point Britney flies around in the air hanging from an acrobat dancer person!
Also there are some pretty good videos of her to watch whilst she gets changed etc (look out for Marilyn Manson, Sweet dreams and also loads of clips from her videos)..also her outfits and amount of costume changes are impressive and sexy! Also I wasn't sure.. but for one routine I think someone from the crowd was picked out (they had a Britney tour tshirt on?) and Britney danced around them on stage. I couldn't work out if this was a 'plant' or a dancer though lol as it all happened pretty quickly!

The only less positive points were I maybe hoped for more off the Circus album but as I said she makes up for this with performing the older songs. and also to be honest 'Everytime' was the only song done live (when she wasn't dancing around), but was done beautifully. But in fairness she does loads of energetic routines in killer heels and we all kind of expected this anyway. Also it thought maybe she should have had some more crowd interaction..she only addressed the crowd twice I think..in my personal opinion from previous concerts i've been to I think it's nice when artists address the crowd and show their gratitude for coming etc. It sometimes seemed like she was on a mission to do the setlist dancing etc, so it didn't seem to flow as naturally as for example Pink's Funhouse tour did.
