Growing up in Minnesota, I spent at least as much time listening to WLS at night as I did to our local Twin Cities stations. Actually, more, since I was in the nighttime null of both WDGY and KDWB. First came John "Records" and Jeff Davis, then Tom Kent. Great jocks, all of them!
Somewhere, I have a tape of T.K. from March, 1980. The previous song ends, the jingle plays, and Van Halen's "...and the Cradle will Rock" begins. Tom proceeds to talk the intro and hit every one of the multiple posts (all of David Lee's screams and various utterings.) Nails it perfectly! Very cool stuff...not to mention hearing Van Halen on AM radio!
