In the verses and the choruses:

D alternates usually with Gmaj9
F# alternates usually with F#7

Listen to the track for pattern, the chords alternate only by taking the
index finger off the frets. It's fairly straightforward. I wrote the song
down with the chords in fixed places so you could get a feeling of how the
lyrics are phrased, hope it helps.

Intro: 

D/Gmaj9 F#/F#7 x 2

Verse:

                     D
                  Im down at the bowery, oh Lord oh Lord
                     F#
Gonna tell you how I got here
                     D
       First I gotta shoot some dice and win
                     F#
            So I can get my room again

                     D
             It  all started with a love so true and the angels flew
                     F#
         Higher than Ive ever been
                     D
              With a sparkle in her face and her eyes and the butterflies
                     F#
         It all came rushing in

Chorus:

         Bm              A                    D    F#
              Buttercup,   I lost my wife in  73 
         Bm              A          D
           She took ill,   she done died on me
         F#
 And Ive nothing more to live for

Verse:
                  D
               So I packed up a bag and went
                  F#
   I just started wandering
                  D
     I hid in the booze and the shadows of the night
                  F#
   I just started crumbling


Chorus:

         Bm              A                    D           F#
              Buttercup,   I lost my wife in  73   
         Bm              A          D
           She took ill,   she done died on me
         F#
 And Ive nothing more to live for


After–chorus:

D                      F#
Oh, it just  dont seem fair...
D                      F#
I met her under a chandelier
D                      F#
And time and space changed from there

Chorus:

         Bm              A                    D           F#
              Buttercup,   I lost my wife in  73 
         Bm              A                    D           F#          
           She took ill,             she done died on me
         Bm              A                    D           F#
              Buttercup,   I lost my wife in  73 
         Bm              A                    D
           She took ill,        Lord she done died on me
         F#
 And Ive nothing more to live for

         F#
 And Ive nothing more to live for
         F# (no F#7)               G (barred)
 And Ive nothing more to live for
