I been playing the horn fills with my left hand (apologies to the horn purists, but hey it's a cover band) and comping between the two chords with my right (EP sound). Can't recall the chords I think Am7, Gm7? Haven't sat down with the slow-downer yet to pick out specific notes and timing. The horns are the prominent audible part for me.
I do the exact opposite.
Layered EPs Bass Clef Zones, and BBB & CHeinHorn layers Treble Clef.
Stomp down an expression for a reverse Delay on A min 6/9 to save me from boredom too.
Ive played that song more than the Commodores I think.
FWIW I play a C Maj. 2nd Inversion, to a D Maj 2nd Inversion as the comp.
