Here's my tab for Bloc Party's Song For Clay, off the new album. It's... nearly perfect, I guess.

Guitar 1: Kele Okereke
Guitar 2: Russell Lissack

|Intro|
'''''''

       Bbm           F           F#      C#   G#
'I am trying to be heroic in an age of modernity

      Bbm           F                 F#          D#m   D#m7
I am trying to be heroic 'cause all around me history sits

      Bbm           F                 D#m         C#   C#M
So I enjoyed and I devoured flesh and wine and luxury

          Bbm          F               F#      F#
But in my heart I am lukewarm, nothing ever really touches...

Guitar 2
I guess it's not possible to play it exactly as it's in the album, so, just use a wah 
or pitch shifter -1 to mess around on this first bit.

That's it, hope it was any help. Sounds nearly perfect to me. :)
