Just wanted to add my appreciation to the guys for mine and my boyfriend's first NIN gig. I bought two standing tickets for his 30th birthday and we damn well enjoyed it.
The O2, in our opinion, was quite good. No waiting outside, decent food and drink (compared to most other venues that charge the same price for poor quality crap). We weren't too bothered about getting in early so we had a few pints with our two friends who got god tickets (seated). Went to the F entrance and within two minutes of getting to the back of a long queue, a lady said if we went to another door, we could get in quicker. I did feel sorry for those that queued for ages

Managed to catch two songs from Mew.
The Good
The venue - clean, plesant, and staff we came across were polite.
JA - Their energy was awesome, set wasn't too bad in my opinion
NIN - Don't really need to say much, from what I saw, they all looked happy like pigs in shit. Sound was great. Like some people commented, intimate gigs feel better, but I'd rather have one larger gig of top notch quality than 10 intimate gigs of exhausted band.
Gary Numan - I echo what everyone else has said. Might go and see him at the end of the year as he's touring
The Bad
Pizza Express - had to wait over 30 minutes after them taking our order before they told us that they'd started cooking it. Granted it was busy, but they had huge ovens.
Random girl - wearing this flowery type dress, looked quite dolled up for a gig and out of place. I've got nothing against being individual, but I doubt she would have looked good at the end, it was damn warm in the pit
6"1,000,000' blokes - I saw about the last 10 minutes of the gig with my own eyes as I had 3 huge blokes infront of me. Again, it's not a complaint, they can't help having lovely long legs, but they didn't even move/jump/sing/mosh/be like the rest of us loonies until Hand That Feeds was played.
The crowd - To us, it seemed a bit tame. Maybe most were expecting the more known tracks, who knows. There was also one couple near us that just talked throughout the whole gig, why?!!
Camera's - I wasn't sure whether I could get my half decent camera in, so bought a pocket sized one, only got asked if I had bottles or cans in my bag. Oh well
Missing - the great stuff on stage. I'm reading about it all and feel gutted I missed it.
The Ugly
Withdrawal - Post gig depression
Illness - morning after I was sick, and now have flu, worth it though!
The First, last, everything - Our first NIN gig, after missing / not having the money / time off work, that will probably be our last, but what a gig to remember.
On a side note (to stop waffling on), the girl who posted a pic of her eye liner sin make-up, that's awesome!
Right, I think that's it!! (sorry it's a bit long..)
