From Jerry's bio, Burning Up the Air. It mentions WROL and Alex Canavan, saying the station had a good spot on the dial and some power, and Alex rented out time. It says Alex asked Jerry if he'd be up to do one hour per day, 2-3 pm, if he was up to it.They could even do Friday's live from Tecce's.
"Incredibly, he did it. On 12/2/02, he started the new show, sitting in a wheelchair from a studio in...Marina Bay. The voice was as thin as his hair. Canavan knew right away it wasn't going to last. Over the next few months, Jerry was on the air less and less. By February, the ROL experiment was done."
Then it says Jerry was invited back to RKO one last time, on March 1 of that year. Jerry died in April of that year, 2003.
