Thanks MarioD for your suggestions.
This Memorial Day morning and afternoon, admittedly out of frustration, I decided to re-create the song from scratch, figuring something must have gotten corrupted.
It took a little time, and as usual many presses of the "play" button to get an acceptable performance, but happily I have my play along track, and a realization that I need to be more fluent in the "ALT" scales. Sometimes thinking of an ALT scale as the 7#11 a tri-tone away helps.
Thank you also Audio Track for your help. My apologies to both of you for your time, only to then see me wiggle my way out of the problem.
