From the absolutley ridiculous (in a good way) album, "In Rainbows".  Beautiful song, 
entitled "Big Ideas (Don't Get Any)" back from the OK Computer sessions.

Any comments/corrections/etc recommended.  Hope that this helps and that you enjoy.

You've gone off the rails.

Em               E
So don't get any big ideas
F       C         Am             G

Dirty mind is thiiiiiiiiiiii-iii-in-king.

[OUTRO - PART 1] 3:10-3:45 of elapsed time
Play the following during the first part of the outro when the layers of Thom's voice 
"OOOH-OOOOH"ing up and down the scale:

Em-F-Em-F-Am-F

It simply repeats between Em and F, but switches to Am the 3rd and final time through 
two-chord phrase.

[OUTRO - PART 2] 3:45-3:56 of elapsed time
When the "OOOH-OOOH"ing slows down.

C-Fm-C-Fm

[OUTRO - PART 3] 3:56-end of song
Unusre about these last few chords.  Three unknown chords, then definately ends on a C.

Best guess:
Just steps down from F to C.  Some sort of arrangement of the following chords: F, E, D 
C
