Joel Sebastian, J.J. Jeffrey (first show) on 89 WLS Chicago | 1971

Almost 18 minutes of pure heaven. Thanks again to Matt @ Big Apple Airchecks, a huge slice of WLS!

Included: tons of early 70s commercials and those awesome WLS Jingles! J.J. Jeffrey would go on to station ownership later in his career. WLS would go on to number one status later that year.
