It's been a while, but I have remixed this and fixed an error in the melody line at 00:31 and 02:10. I've replaced my Sound Canvas cello and viola with Spitfire audio Abbey Road 2.
Referencing the comment by steve@baselines.com, there is no Cm chord in this song, so I still don't know what he is referring to. Right at the start there is an Eb chord (2 beats) followed by a D chord (2 beats). I play Eb notes over the Eb chord and a D note coincident to when the D chord starts. A bit later (~15 secs) I play an Eb note over an Ab-add-9 chord. I believe this is all correct and sounds right to me.
