This is from memory, so it may very well be wrong, I encourage anyone to correct me.
Intro:
Bb/C > Cb/Db
Lead in:
Gb > Db/F > Ebm : ||
Chorus:
Gb > (Bbm) > Ebm, B > (Ebm) > Abm : ||
Verse: Cb/Db
Notes:
-All minor chords can be minor sevenths, the I and IV can be major sevenths. The Cb/Db chord might have some extensions in it like a sus4, I dont recall.
-The chords in parenthesis are passing tones
-Cb is a funny name, but if you're in Gb, that's what you call it, because you already have a B. If you're in F# then the chord becomes B/C#
-The guitar doesnt hit all the chords the bass does. In the chorus, I think it plays the same chord over Gb and Ebm, and then the same chord over B and Abm. Except for the root, those chords are the same. I dont think the guitar plays in the "lead in" but I could be wrong.
