Here's a memorable commercial for the White Sox - featuring fans singing "Na Na Hey Hey Kiss Him Goodbye" by Steam, first popularized during White Sox games by team organist, Nancy Faust. Featuring a young Kathy Griffin (in her first acting job, years before making it big as a comedian and TV personality) wearing braids and Sox hat and playing a kazoo, all the way at the far left of the screen in the second row around :15 (among the attendant Sox fans), and Theodore "Ted" Noose as the traffic cop at :10.
Ending voiceover by Don Criqui.
This aired on local Chicago TV in early 1978.
