Word this morning that John Mack Flanagan (KTKT, KRUX, KFRC, KCBS-FM, KRQR, KWSS) passed away last night. He'd been in ill health for more than a year and was initially given only two weeks to live. He was at KFRC from 1973-79. Flanagan's last radio gig was a Sunday Beatles show on the short-lived revival of KFRC on 106.9 FM in 2007.
