Regarding my original 'lead' on the Armstrong cite, which came from "an older woman" who came up to me while I was playing tinwhistle in Propsect Park in Brooklyn last Sunday, I am beginning to think she may have meant the slide whistle, not the tin whistle. The Les Lieber/Django Reinhardt stuff is much more intriguing. It turns out that as recently as last year, Mr. Lieber was still hosting a Friday afternoon jazz show and performance in midtown Manhattan. The website advertising the weekly get together--in addition to listing his citations from about three New York City Mayors and acknoweldging his contributions in general--shows him playing a (new looking) Generation F whistle!! Also, thanks for the suggestion about Bill Ochs, with whom I take classes. This has sort of arisen out of that context. Thanks, Tom D.
