Greetings Rick; With all due respect to a fellow mudcatter, you have some facts wrong. Paul "Hezzie" Trietsch played the slide whistle (what Louis played on the Hot Five session you mention)jew's harp and washboard. I have very nearly everything the Hoosier Hot Shots ever recorded, and I'm pretty sure(of course, I could be wrong)that the Kazoo never appeared on even one recording. As far as starting a thread on the slide whistle, I don't think we're in any danger because there have never been that many players. Now back to Kazoos, for hot dixieland comb and tissue paper/kazoo duets, check out the Mound City Blue Blowers. As far as great musicians playing questionable instruments, how about the many times Jimmy Dorsey held his thumb over the tip of a bicycle pump air hose, for "Hot Bicycle Pump" solos?
