Here’s a gem that Torontoist found: an except from a 1974 travelogue featuring Steve Martin called The Funnier Side of Eastern Canada:

Younger readers may not be familiar with this incarnation of Steve Martin, who was then best known as a stand-up comedian specializing in absurdist routines. This is pre-Man with Two Brains, pre-The Jerk, pre-King Tut (“Buried with a donkey! / He’s my favourite honky!”), and even pre-“Crazy Czech brothers” Steve Martin improvising his way across the city – I’d love to see the rest of the film sometime.
