I would just like to say how happy whistles have made me 
I pick one up!
I play it!
I get happy!
Same with me, John. Whistling has been a very positive addition to my life this past year. When I play, I get happy. Even when I’m not playing – for example, when I’m attending a boring meeting at work – I can recall whatever tune I happen to be learning, listen to it in my head, and visualize the notes on the sheet music and my fingers moving on the whistle. I imagine myself sounding like Brian Finnegan. That makes me happy too. Or maybe that form of “remote" practicing simply makes me a candidate for the Art Bell show.
