Funny, I was having a conversation last night on the subject of making music by putting things (not possums!) in your mouth. I recall a British jaw's harp player made an album in the sixties or seventies of ethnic JH-type music from all over th world. One that stays in my mind (the only one!) is an African instrument. There's this fly in Africa that has a very loud and constant-pitched buzz; they tie one to a stick, and it tries to fly away for an hour or two before it becomes exhausted (flies are pretty stupid), and you put the noisy end of the stick in your mouth and off you go. Don't try it with bluebottles, unless you know where they've been.
