Why am I not surprised? - I am into music, and the same thing is true with
that art, too. A friend of mine and his group plays Dixieland jazz at the
local pizza parlor once a month. The other day he told me that some
organization that has copyrighted all the music ever written threatened to
sue the manager of the pizza parlor for letting his group play there. He
will have to pay them $500 before they will "allow" him to let them play
"their" music.....Since they own the copyrights to every song written during
the last 100 years or so, he has little choice but to tell my friend that he
can't play there anymore. These people couldn't write a song if their lives
depended on it. They are just making money off of the artistic talent of
others, most of whom are long dead and gone. At least, the operators of the
racetrack will still allow you to go there and take pictures........In the
music business, the fact that the pizza parlor does slightly more business
on that one night a month that my friend plays there is enough to force him
to stop the music. The racetrack owner might have to prevent anyone holding
a camera from entering the track property based on the off chance that
someone might  only go there because he likes to take pictures, so he is
making money off of photography, and they (apparently) own the photography
hobby.....Perhaps they have obtained copyrights on every scene on earth, so
no one can take a photograph of anything without violating their copyright
on it......It wouldn't surprise me.....I can't walk down the street
whistling a happy tune without some lawyer jumping out with his tape
recorder and yelling that he will see me in court......
