"Red Green" was the first Canadian television show watched in space, when a copy of the "Best of Red Green" video was brought to the Russian space station Mir. The video was trapped in the Spektr module following a Progress collision, and thus was never recovered. The videotape is now presumably at the bottom of the Pacific Ocean, along with the rest of Mir.
Bernice (Red's wife) is mentioned in almost every episode, but has only appeared onscreen once - and even then, we only see her hand and part of her arm (peeking around from behind the front door of their house).
In the first seasons Harold was seen many times with what he referred to as a video controller for the show, which he had slung over his shoulder like a guitar. The controller was in reality the control panel off of an Ampex VR-2000 2" (quad) video tape machine with a set of rabbit ears attached.
