Ooh yes, Kazoos!!! I love 'em. I'm trying to get Hammerite to forsake her Djembe for a couple of songs & be my horn section instead. Seriously, you can get some great bluesy sounds out of a kazoo if you slide the notes.
Best of luck with your ensemble.

PS - has anyone else tried those plastic telescopic didge things? They are really wicked (Hamm quote)
