I agree with the previous statement that he was not at the top of his game here. I've heard some WCFL airchecks on reelradio.com, and remember hearing him on CFL when I was stationed there in the Navy 1968. Am I correct that a few years after this, he was on a station in Montgomery, Alabama ... a much smaller market after being in Chi and NYC.
Those PIX jingles are some of the worst ones I ever heard.
