All you do is play G D Em throughout. At the end of the chorus, "Is how good you are to me", it sounds like there's a different chord. Maybe Am7. But you can just play the Em and go back to G and it sounds fine. Lyrics:

^GWhen everything's said and ^Ddone Your ^Emall I really have In the ^Gmidst of these setting ^Dsuns The ^Emcity lights at best Are ^Gportraits of my ^Dfriends But ^Emthey don't make amends For this ridiculous ^Gmess^D ^Em

^GSo I will ^Dfloat on ^EmEvery word you said When the ^Gwater of my ^Dghosts They ^Emrise above my head And I will ^Gstand up on your ^Dback In the ^Emmiddle of this sea When col^Glectors of my ^Ddebts They ^Emcome to sink their teeth

And its ^Gall I can ^Dthink about ^Emnow Is how good you are to me^G ^D ^Em
