Radio lost one of its greats today as Chicago legend Larry ‘Superjock” Lujack passed away at the age of 73. The former WLS and WCFL star had been battling esophageal cancer.

Rush Limbaugh was quoted in a 1990 NYT story as saying Larry Lujack was "the only person I ever copied." #RIP #Superjock

Larry Lujack was an incredible talent, a sensitive, caring gentleman. He was meticulous, a pro who understood everything was in the details.

I got sent to the principal in 2nd grade for repeating something I heard Larry Lujack say on WLS to my teacher. My truest radio idol. RIP.

This is exactly what Larry Lujack had to do in 1976 when WCFL threw in the towel. The sarcasm oozes from this clip: https://t.co/Cd3ZMSuehv
