Sounds great. I DIG the bass.
Chord voicings...on this one, just fill in the blanks. First four chords of the A section...the melody line has that beautiful ascending movement, so avoid that in your upper voicing. But, it leaves you wide open for a sweet descending voicing. Ab (Fm) - G (Em7b5) - Gb (Ebm6) - F (Dbmaj7) with whatever chord tone you'd like underneath. Just avoid the root, as it takes away from the bass line. The next four bars are just a ii-V turnaround, so you can get tight if you'd like (i.e. F&B-natural to E-Bb to cover the G7 - C7 ground).
I hereby sentence all of us to an hour each of Jaco and Victor, lest we forget the harmonic possibilities of the four-string.
