I was standing by the wall at Ballanorris when Joey whistled past behind me! He slid off the bike which rolled and tumbled across the stubble, shedding bits as it went - tank, airing, exhausts - you followed the trail of debris and came to the remains of the bike.
Joey got to his feet, walked to the wall (probably cadged a fag) and watched the race continue.
Nigel McC recalls sitting on the remains when he cadged a lift back to Ireland after the meeting.
The story I heard was that the steering damper jammed.
