"For the Pigeons That Here" is a snippet from 1970s Chicago cinema history.  The movie entitled Cooley High was the first "black" movie filmed in the city of Chicago.  The success of this movie led to the television show Good Times, which was about a families struggles living in the Cabrini Green projects of Chicago. As a child, I would sometimes wake up at 1am , and I'd turn the television to channel 9, and Cooley High would have already started. 
So, growing up before we'd take a drink of whatever liquor we purchased, we'd pour a little of the contents out on the pavement in the remembrance of this movie and friends we had lost along the way
