No idea, but I thought he went on to an acting career. I recall "Switchback" being hosted by Rick Scott at one point too, and I thought Stu Jeffries before he went over to "Good Rockin' Tonite" but I could easily be wrong about that.
Searching the web and I find a story on Eric Tunney who was said to have done a stint on the CBC show Switchback. He's a comedian now? Link to story below.
Something slightly different for your Easter Sunday - a quad of radio station ads (CJOR, CKNW, and CKWX) all from 1980 as well as a TV Guide piece from 1983 on CBUT Newscentre co-anchor Cecilia Walters.
A bit of CKVU, BCTV, CBUT, and KVOS from 1980 - 1984.
I fondly remember CKVU's habit of broadcasting films uncensored. A common practice today back in the late 1970s-early 1980s before the advent of pay TV or cable packages it caused more than a few raised eyebrows. Where else on the initial cluster of channels could you tune in to see movies like "Up In Smoke", "Big Bad Mama", "The Texas Chainsaw Massacre", "The Sailor Who Fell From Grace With The Sea", "Alvin Purple", or the "Emmanuelle" films?
