This is a very straight forward song.

The chords used in the opening and verses are repeated :

F Bb Dm (x2)

You can also play it as

F Bb Dm Dm/C (Use a C for the bass note)


The chorus:

Bb A7 Dm


I assure you these are the correct chords. It's a great song -- Aimee always finds a way 
to write magnificent songs with only a few chords. Cheers!
