This was one of Fraser's ideas before he left the blog, to post classic Muay Thai bouts. I stumbled on this particular trove of classics surfing one of China's viral video sites. It's a great way to familiarize yourself with better known fights from what's known as Muay Thai's "Golden Era," namely the 1980s and 90s.
The two biggest promoters of Muay Thai in Thailand are OneSongchai and Petyindee Promotions. Think Golden Boy and Top Rank, except they consistently make competitive matchups at the highest level and will co-promote. Scratch that. Don't think Golden Boy and Top Rank. While the two Thai promotions appear to have some history, they operate quite differently from the two marquee U.S. promotions.
The Best of OneSongchai is exactly what it sounds like: a compilation of the best fights put on by the promotion. The series is quite old, and I'm not sure how many volumes there are. Volume 1 is full of great matchups, starting off with Ramon Dekkers in his 1990 upset against Nampon Nongkeepahuyut.
Also in the video: Sangtiennoi Sor Rungrot vs Namkabuan Nongkeepahuyut, complete with all three people in the ring, including the referee, tumbling over the ropes in round four. That's at about 24 minutes into the video.
The bouts in this volume are fought under a slightly different ruleset from modern Muay Thai. The technique known as plowing, wherein a fighter catches an opponent's leg and pushes him across the ring, is now illegal. It can lead to instances like the one at 46:20 where Rainbow KOs himself by flying over his opponent's head with a high kick. I believe the maximum number of steps is now three.
The full lineup is as follows:
Nampon Nonkeepahuyut vs Ramon Dekkers;
Wangjannoi Sor Palangchai vs Cherry Sor Vanich, at 11 minutes;
Namkabuan Nongkeepahuyut vs Sangtiennoi Sor Rungrot, at 14:20;
Sakmongkon Sitchuchok vs Jongsanan Fairtex, at 28:30;
Den Muangsurin vs Rainbow Sor Pantalay, at 41:50;
and Pongsiri Por Ruamrudee vs Pirotnoi Sor Siamchai, at 48:20.
