It's an ESPN TV-Programm based on rare footage recorded and saved from that great game. It's not a whole game (I'm not sure if anybody has the original full-lenth broadcast) but the big part of it. It has the commentaries of Doug Collins (1972 USA Guard) and John Bach (1972 USA Coach Assistant). The quality of the game is amazing for those times & commentaries are in English, so have fun!
