I am sitting here on a Friday afternoon blowing off class (I have the same bug cowtime does) and I’m watching a Dixie Chicks DVD a friend gave me, called Top of the World Tour Dixie Chicks Live 2003 and I really like their music. It occurs to me that a lot of their music, particularly the fiddle parts, might be playable on a whistle. What say you all?
Dixie Chicks really gets your feet moving . . . . grab that whistle and play 
Sure, Cran, why not?! There have been a few threads recently on using whistle in American music. And the Chicks themselves use a whistle and fiddle duet on the intro to “Ready to Run” (Fly). If you want to play along, their recorded keys are all over the place. But a D and C whistle are enough to start.
I watched the whole DVD and didn’t see a whistle…hmm…I didn’t think I heard one either, but cold medicines can make you wacky. 
Yeah, that’s probably only on the original album version. But here’s a video with the fiddle and whistle intro. And at around 1:47, and from 2:50 to the end, you can see and hear a guy playing what looks like a Susato in the background.
Thanks, everybody. 
I’m pretty sure the guy playing whistle on all that Dixie Chicks stuff is John Mock. (http://www.johnmock.net/) I talked with him at a rehearsal once and was surprised to see how much he’d modified his whistle. He opened some of the holes a bit and used tape to close some of the other holes. Being active in Nashville, I’m betting he’s expected to be pretty tight with equal-temperment. He always sounds very “in-tune” to me on the Dixie Chicks recordings.
