If you look here http://www.museandamuse.com go to songs click on TAB and then piano > Bliss, there is a guide how to play it on piano.
Also in Electric Guitar TABs click on Bliss. number 1 is a bit of TAB then the Chords, and number 2 is the whole song fully tabbed.
I do have the book so if i can get my scanner to work I'll scan it in for you :)
I was at the London gig, quite close and a bit to the left of the "normal people" section. I was really annoyed at that too and it did look really crap cos everyone was crammed in the "normal" part and then the people who paid didnt even fill the area and there was a massive gap. Still was an amazing gig, Coldplay were amazing as were the killers and razorlight and stereophonics. Although it would have been even better if Muse had been kept on the London bill.
