To catch John's style (I known him all his playing days) you have have to from learn where he starts his music.
His opening chord is an Eb maj7 3rd inversion = D Eb G Bb with an F bass.
Followed by a melodic line of Bb, C, D (part of the Bb scale)
Left hand chord Eb maj 7 root + Eb G Bb D
The run (roll the C^Db,D) - C^Db,D,Bb,G,D,D,C,Bb,G,Bb
Ending chord left hand Dmin 7 = D F A C
Bass note is Bb
Yes, it's impossible to write another musicians style so you have to take it note by note, chord by chord and add the bass.
