My friends and I made our own riffs at CTV when it was attached to Irondale. Used to play on cable in New Brighton / Fridley / Mounds View / Blaine in the mid-90s.
If you ever watched some nerdball teens riffing on OCTAMAN, DRACULA VS FRANKENSTEIN or THEATRE OF BLOOD, let me know. It’d be fun to find someone outside my circle who has seen one.
