Thanx a lot, Bob..
You're right, placing a D instead of those slashes is better, at least in terms of reading and understandibg, it's clearer.. in fact the chord starts at the last beat of the measure and is continued on the next measure.. What would be needed is a tie..

What I'm not sure of, in my transcription, are the (Bb C) and the (Eb C) at the end of lines 1 and 2..
And also the repeated (Gm7b5 C F) in part B..

And btw, there are a few videos of this tune on YouTube, studio and live, plus one cover..

Have a nice day..
