Tune guitar do drop D tuning (the low E string down to a D) and place capo on first fret.
I have no idea what the name of these chords are, so be patient with the names.  The tabs are relative to the capo.
This is by far the most involved David Gray song I have come across in terms of difficulty to play and figure.  It really has some nice chords in it.  This one will involve some practice, especially getting used to that shift from the G to Asus2.  Hope this is useful.

Chord info: (remember, the lowest string is a D not an E)
