I was at Mountjuich that day Joey won the F1 and Brian Reid won the F2.
I never saw Tony's crash nor did i know about it untill we got back to Ireland. A few years later I bought a t shirt at the Ulster to help raise funds for Tony he was a great rider but the 350s were too much for the Ducati twins in the end.
I was also in the paddock at Mountjuich trying to find Joey the cop on the gate would not let us in untill one of the Rothmans Honda guys spoke to him for us we ended up staying in Joeys hotel that night and drank till dawn.
The man to speak to regarding F2 350 Yamahas is Billy McKinstry Some of the stuff he did was copyed by Yamaha years after he did it. He also told me a good story about Tony but I'll save that for another day
