We all know that has since changed. US 99 wanted a younger morning show.
When WLS let Ray go at the end of last year, I believe his contract was up. I think he would be free to work at another station now. Maybe he will show up at some point on US 99 as a part time/fill in person. At this time he is off the air.
Big John is still on WLS because he and Ray got contracts at seperate times. I suspect(and this is just speculation on my part) that when Johns' contract is up, WLS will let him go and plug in more syndicated "stuff".
Sorry for the long post, to sum it up, he is not currently on the air. Keep an eye on this board, if he gets back on the air, someone here with mention it.
