Alex, I had been thinking about you, and it just came to me what it was about; "Bud Shank, "Koto and Flute". I'm still trying to find it, but as close as I could come.

There is a music link that sounds quite similar; as it gets near the end, that flute sounds a lot like "Bud Shank"

I listen to this as a substitute for "Bud Shank".
Enjoy the music
