Spike Jones/Earl Bennet/Sir Frederic Gas/Sadivarious.

[squidgelet10]

Hey guys:
I am trying to find some information about HOW the 'Sadivarious' worked. It was used by Earl Bennet, who toured with Spike Jones and His City Slickers under the name "Sir Frederic Gas". He wore a black suit with long tails, a string necktie and teased his long hair out into a "fright wig". His comic specialty was rubbing two sticks together, while squeaking a leather reed in his mouth, creating a comical instrument he called his Sadivarious.
Any ideas please?
Cheers.
