Ahhh that explains it. People in the rest of the world not familiar with Gary Fischer would be like "where the heck did this come from?"😳. I'm too young to remember but I know he remained very famous even in the uk for years later.
Watchtower is so America-centric (if that's a word?) and of course they'll try to ban anything popular that will distract the sheep.
