To everybody's surprise (including TVO's) Yost's show became one of the staples of Saturday evenings and at times drew almost even with Saturday NHL hockey. So popular did he become that rivals deliberately bought away huge blocks of movies to keep Yost from getting them.
Yost always told me his biggest disappointment was never being able to run old Warner Bros. titles because CBC owned the rights.
After Yost retired TVO repackaged his interviews into a "new" series called Film 101. It's passing strange to me but Uncle Elwy's name nowhere appears in the credits. Also overlooked is his long standing producing partner Risa Shuman who continued to run Saturday Night years after his own retirement.
Elwy's absence is in name only. You can still spot his distinctive voice and "Gosh Gee" interviewing style in a majority of interviews. Is TVO embarrassed or what by his continuing fame?
