BBC iPlayer - Witness: Tragedy on the Tour de France
I'd never heard of Tommy Simpson until fairly recently but I've known his former mechanic for many years, Harry Hall.
I know at least one person on the forum with a Harry Hall bike. I bought a bike from Harry's shop in 1986 but I couldn't afford one of his actual frames.
