The people making Fubar probably knew

A while back as part of the Bluesfest guide, dial613 posted a New Pornographers track that was only ever released as part of the Fubar soundtrack. It didn't really sound like an original, but there were no means to verify the hunch (read: lazy).
But after endless detective work and tireless investigation efforts at dial613 control center (read: soulseek 24/7), the original has finally been located. And, as always, the fruits of dial613's labour are yours to enjoy.

From 1982's Get It On Credit by Canrock band (and ungoogleable) Toronto:
--->Your Daddy Don't Know

--->The New Pornographers - Your Daddy Don't Know

Who wins?
