I have a vivid and frightening memory of watching Polka Dot Door on TVOntario in the very early 80s (or was it the late 70s?) and getting spooked by the opening theme of Doctor Who.
I first wrote about this scarring memory almost 7 years ago but now, thanks to Retrontario, I can share footage of exactly what I remember.
It's still difficult for me to watch. That Doctor Who opening still freaks me out.
