It’s my own arrangement, and I don’t have anything written down, so I’m just going by watching it again myself.
It looks like I tuned down a whole step, but fingered it in the key of F —
F7(2313) Bb7(1211) Bb9(1213) Bb13(1231) F7
then slide Gb9 to G9 (3444)-(4555) C7(3433) C7#5(3443) E7b5(3445)
F7 Bb7 F7 slide G#9 to G9 (5666-4555) C7 (C7#5 E7b5)
the turnaround uses C7dim (5656) G9 C7 (C7#5 E7b5)
