Note to editors: I submitted this a few days ago but then realized all the Ab6 
chords are actually Ab7. Below is the corrected version. Please replace the old 
one. Also why was Gb changed to F#? Please leave Gb as is, since it's more natural 
to see all flats in a song. THANKS!

I think these are pretty accurate chords. To play it like the Fiona track, pay 
attention to inversions. Enjoy!

[Note: Fdim7/Db can also be thought of as Db7(add9)]
