(Intro)
trying to work out this song.


on the piano the root chords of the song are

worked out the intro

just this repeatedly picked for the intro and the first verse

E|--------------------------|

G|-----9-----9-----9-----9--|
D|--------------------------|
A|--7-----7-----7-----7-----|

then i get stuck when the chords kick in for the first chorus.

Cm deffos sounds right for the 2nd chord but im not sure about Eb as the first and the 
and fouth are giving me difficulties.

if anyone can look at the chords i worked out on the piano and make better sense of it 


cheers!
