Thanks, I'll try that and tell you what I find
I'm not sure what you mean by 'broken chords', but I guess is something similar to what I do (except what I do is sounds a bit poor): if a bar is 8 eight notes, I do something like:
2 higher notes - lower note - middle note - - 2 higher notes - lower note - middle note - - 2 higher notes - lower note
And I relieve it somewhat by elliding some of them (at phrase endings), and vary it a bit some times (though I wish I knew several ways to vary that).
I'll try about voicing the whole chord on the downbeat.
I'm playing the intro straight from the transcription

It's very nice and recognizable.
But I don't get the part on the G changing function. Maybe it's my transcription? I can't see it. You mean on the second bar of the intro, or on the sung part?
Best regards and thank you very much,
