Hey Jerry, Is that really an Fm7b5 bar, though? That would imply that a B is being played in the chord. I hear a C (which implies Fm7) in the keyboards and in the horns, not to mention that Stevie is singing "o-o-o-ver" back and forth between Bb and Ab, which would mean that he is a half step above and below a B-note for that phrase. What instrument is playing the flat 5? Sorry, but my band is debating this one right now. All I know is that the guitarist is playing the flat 5 and I always feel strange singing over it, not to mention playing F-Bb-C as already mentioned. The sheet music that I've been able to find has Fm7, but we know sheet music ain't always right. Thanks!
