Jim,

sounds absolutely marvellous, although listening to the first few bars I was expecting : " Don't know much about history,etc........What a wonderful world ........" .
So suprise there, but a pleasant surprise. Great to hear any Arrangement that shows orginality and shies away from the obvious. Also, I think you should hang on to your PA3X ....possibly add a Roland EA-7.......

regards,
John

P.S. I did a version of the same song in 2015, still on Box:
