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!
