I love this song and am surprised there isn't a tab already for it.
Since there's nothing online I see yet I quickly penned out the 
chords so you can play it. The whole thing revolves around 
F#, B, and C#. I usually play them up higher on the fretboard 
on the 9th fret. Standard tuning duh.

Intro
F#

F#               B                 C#
I've            put               on     something
you           can't  switch off

verse
F#
I won't buy, you won't cry
B                              C#
I know i will and you know how it feels
F#                            
on the northside on the southside
B                                       C#
they sing along long when you switch on

break

chorus
              F#       
You switch on for the city
        B                  
long gone from the city
                                     F#
come on strong winds move on
          F#
you belong in the city
      B
I'm long for the city
                                      F#
switch on a sad song when I'm gone

when in new york
I stay indoors go into the city 
and switch up the pity
on the train someone says
something about how jesus saves
but I'm too lost to be found
you put on a good face, when i wasn't around

on the eastside
on the westside
they sing along when you switch on
You switch on for the city
long gone from the city
come on strong winds move on
you belong in the city
I'm long for the city
switch on a sad song when I'm gone
