In 1972, Jerry Vale was the kind of guy who got played on your parents' favorite radio station.
My generation did not willingly listen to these stations in 1972, nor did we willingly watch the Jerry Vale's World special on TV that year.
Don't think that stuff didn't have an impact, though.
It had an impact on the creative forces behind SCTV in the late '70s and early '80s, and it had an impact on those of us who howled with laughter because we got the joke.
