I need the source (article, book etc.) and publisher for Hunter S.
Thompson's quote: "The music business is a long and shallow money
trench where pimps and thieves run free and good men die like dogs.
There is also a negative side."

Well, someone else has done the digging on this one. Below is the
pertinent information, along with a URL for an article in the Urban
Legends and Folklore section of about.com, written by David Emery in
response to a question like yours. Apparently this quotation has
appeared in a number of guises on the internet, including the one you
cited in your question.

Original quotation:

"The TV business is uglier than most things. It is normally perceived
as some kind of cruel and shallow money trench through the heart of
the journalism industry, a long plastic hallway where thieves and
pimps run free and good men die like dogs, for no good reason."

Original source: a bylined column in the San Francisco Examiner on
November 4, 1985. Reprinted on page 43 of his book "Generation of
Swine: Tales of Shame and Degradation in the '80s," published by
Summit Books in 1988.

The full article, describing Emery's search for the original quotation
and its source is here:
