Yes I searched first.

What is this song about, why was it written, and why is it sung? This is the one that goes something like this here:

Just drop whatever you're a-doin'
Your lone wolf is here to bark for you
The hungrier I get, well
The hungrier I yell (howl)

Just look way down in your pocketbook
Send me a quarter and get yourself a book
The lonesomer I get, well
The lonesomer I yell (howl)
(repeat first verse)

Is the book a bet thing? What is the quarter? Why would I have a lone wolf, and why would it bark for me? I have this on the Cisco Houston Sings Woody Guthrie album, so I'm assuming it's Woody's...
