As a matter of fact I do! :)  There is a video called "The Great Dinosaur
Hunt" (an episode of the PBS series "The Infinite Voyage") that includes
a "music demo" by a researcher (sorry, I forget his name) who has built a 
device that when blown into simulates the sounds that could have been
made by crested hadrosaurs.  I recommend this video anyway!
