this is the way i play it coz it suits my voice, its simple, 2 chords,1 rhythm all the 
through so i've only put the first few chords!

Am7 /G   /

Am7                                  G
When you first left me I was wanting more
                       Am7                               G
But you were doing that girl next door, what ja do that for
When you first left me I didn't know what to say
I never been on my own that way, just sat by myself all day
