I only met Colin once, when he retired at the Highlander during practice cos his bike was making a funny noise, I gave him a push in someone's driveway to start it up again but he decided not to continue. He seemed like a laid back type who didn't take himself or the situaition too seriously. I always maintain that people like Colin make the TT what it is. Never mind how many 'top' names there are or how fast the lap record is, I was more shocked and upset by this news than many other events of recent times.
RIP.
