Thanks to all who responded to my request for information concerning
a cap suitable to wear while organ grinding, and a special thanks to
Hal O'Rourke for the temporary cap.  I have found one on the Internet
that I think will be suitable:  it's called a "Fiddler's cap" and on
the inside it's labeled a "Dutch Boy" cap.

Now I'm all set for the first rally.
