Well, the Yeah Yeah Yeahs made this cover of Bj?rk, they recored it in a cassette tape 
they sent to the great singer (Bj?rk, of course). That songs appears in "Master", a cd 
rarities and etc. The only part that they play is the chorus, so here it is:

     B            (IV 2/4)
I go through all this
 C#      F#     F?
before you wake up
             B  (IV 2/4)
so I can feel happier
C#    F#           F?
to be safe up here with you

(use the same chords that appears in the chorus)
I'm back at my cliff
Still throughing stills off
I listen to the sound they make
Under way down
When my eyes be to close to open

Here nick plays this chords (maybe is not, but it's close)

Ab  Bbm C#   X4

this chords sounds better if you play it with bars, every chord in the song:

B: 224432  or  799877
C#: 446664 or 9-11-11-10-9-9-|
F#: 244322 or 9-9-11-11-11-9-|
F?: 234422 or 9-9-10-11-11-9-|
Ab: 466544
Bbm: 113321 or 688666
