The Jury may still be out on this question Mike. I did find a site that said yes Jim did the whistling om A/A. later I assumed that the Bear book not listing a specific whistler meant that Jim did the job. And now, I can't find the specific page I found this info.

I know there is NO mention in Larry's book about this. Then another site states the whistler is "unknown" and can not be credited to Jim.

Anyone else like to deliberate on this issue. Surely the info is somewhere.
