There's a really well put together documentary on the NJPW/WCW show in North Korea on YouTube. Worth a watch, and I think your readers would enjoy it. https://www.youtube.com/watch?v=U_ZkqfSpbg4
Yeah, YouTube put it at the top of my Recommendation list for like three days straight so I finally watched it today. It was pretty good! Didn’t learn much but it was neat.
