I think it has to do with there are so many users already who have no clue what we're talking about that the question could be how far do they want to go to be classically correct?

Classically trained players go around and around with this all the time. Should you use the classically correct major key or the relative minor key when the song is obviously a minor?

Biab allows for flat key sigs. Put it in Eb minor which is how everybody thinks of it anyway. The bridge/turnaround ends on the 5th of Eb. So the entire bridge starts on the B but then goes to Bb minor which is the 5th, the Ab minor which is the 4th then to the GbMaj7 to the Fm/Bb or Bb which is the 5th. Basically it's just another minor blues that goes 1-5-4 with a couple of jazzy passing chords.
