According to Bryan Sheppard's "Friendlies, Tours & Testimonials" book the game was played in Paris at the Parc des Princes.
During the first half there was a fight involving every player except the French keeper that went on for five minutes before the Belgian ref, linesmen and numerous gendarmes regained control. Throughout the second half the pitch was surrounded by armed police officers, but as soon as the players got into the tunnel at the end it kicked off again. Peter McParland is quoted: "It was a real free for all and I can remember, which I laugh about now, Bill Moore, the Villa trainer being in the middle of it. He was stood on a chair with the the heavy metal pump he used for inflating the balls and was whacking the French players with it!"
Wonderful.
