Wow, I just got form London (late, I know but I stayed there for Valentines) and I cannot express how great this concert was!!!! (forgive my spelling and grammar)
As for the DVD there were papers saying that "Utada live at O2 Academy Islington" (working title) will be filmed on 12th so if you're going to the concert it means you agree to film you for U3, Island Def Jam etc.. I only saw that after the show ended but still
Now for the waiting. The line was super huge and it turned out that I was sooo lucky to pick up the tickets on the day of the concert. The ticket line was quite small and they let us in just after we get our tickets so me and my boyfriend (probably only person in the who didn't even know how Utada looked like) got great spot near the center. I could see Utada so clearly an it was amazing*_*
I liked DJ Marlene, she/he was so weird and seemngly uninterested in public but the music was funny XD Not something you hear everyday, a good mix of different styles and cultures (some french some indian a japanese song form Kill Bill). I agree the flow of the songs wasn't so good but I still danced for the first forty minutes or so:P
When DJ ended people went crazy because we thought Utada is on her way but it still took quite a while for the concert to start. In the meantime a microphone which was put up on the stage got ovations xD Guy who checked if the guitar was working got himself an ovations, too xD
And then the band came to the stage and shortly after them there was Utada and On and On was a BLAST!!! I must say I was dancing, singing and screaming until my stamina let me (and that means until we started screaming for encore). FYI (-London, London! -WHAT! WHAT! XD), Poppin', Passion/Sanctuary (I loved how she forgot she should sing that song xD xD xD) I don't know how people behind us were but up in front people went crazy every song XD And I loved the spanish group, they were so lively:P
As for Exodus stuff it was amazing but I felt that Utada put too much in this section because of how great it was recived by the crowd (it was insane atmosphere during the whole Devil Inside, ending of Kremlin Dusk and You MAke Me(...)). She actually seemed to restrained herself from singing the high notes by the end of YMMWTBAM in order to not loose energy for the rest of the show but even the way she was banging in the drums just before the song ended overpowering
I loved The Bitter End cover, I loved how they ended Dirty Desire. I jumped so hard I think I might have broken somebody's toes with my shoes xD
As for calling out the band for the encore... I was at my limits at that time and so was most of the people. The chanting died like fore or five times, I hope that won't make it to the screen. And just when we were all pumped up thinging Hikki was coming out it was just a stupid cameraman filming I remember that when they appeared again I saw one of them had water and it took all my attention for a while XD XD XD

I also stand after the show waiting for an autograph but the hope died with the speed of Utada's car ;_; Well, nothing can change the fact it ws the best concert ever :P

Oh, and talking parts were just hilarious. Here face when she was supposed to say something but started reading that some girl waited for three days for the concert - priceless. So was the comment. And whe she said she liked cloudy weather. The sky is white and people seem to be cut in the paper and "I'm loosing you guys, you make me feel to comfortable" xD I was seriously trying to picture that scenery she was talking about :P
