I didn't know the man but saw his obit and thought I'd post it here:

"Ron Sweetman, an organizer and champion of Ottawa’s jazz scene since the mid-1970s and a CKCU radio show host for almost 40 years, has died.

Or as his online memorial says, he “peacefully checked into the jazz club in the sky on October 24, 2018.”

Sweetman, 86, founded the weekly CKCU jazz show In A Mellow Tone, named after a Duke Ellington song, in May 1976. He hosted his program until his retirement from radio in September 2015. The show continues, hosted by a rotation of jazz zealots."
