Can't remember the bosses
name, but in the early 60's, I worked for Butler Amusement
in CA; and for a short period, we had the "Zanilla the
Gorilla" sideshow; and a couple of times for a day or two, I
worked for him.
The show was in an old beer truck, with a tent on one side.
We had a door with bars across the hall in the middle of the
truck, and in the back of the hall was a transparent mirror
at an angle, that would slide "FAST". The mirror was shut
at first and in a side panel was a beautiful girl; with
bright lights on her. It looked like she was in the back of
the hall. Behind the mirror was a friend of mine (forgot
his name now) in a gorilla costume. The lights would slowly
dim on her and come up brighter on him; and at a set time ,
all lights would go off a second; and a loud noise would be
heard (the mirror quickly sliding open); then the lights in
the hall would come back on with an amplified gorilla roar,
as the gorilla ran to the front of the hall, and threw open
the door made with bars; sending almost everyone running and
screaming out the exit.
I went to the owners house once to pick up his truck; and I
know it was "near" LA; but I can't remember which city in
the area. While there, he showed me his other sideshows.
He also had a frozen Bigfoot or something to that nature, in
a truck with Hiroshima and Nuclear bomb explosion photos on
Possibly you have records
of his sideshows.
If not, I'm sure Butler
Amusement's records would give you information about his
gorilla sideshow, to update your files.
