Although Professor Diamant died before we had even heard of him, for the last ten years Jack, now in his 90s, has been explicitly aiming to pass on this expertise to Chris, while I help (or often hinder) the process by struggling through the accompaniments of the songs they work on. One of these, Schubert's famous Heidenröslein, was the last song ever performed in public by Diamant, as an encore; he must have loved it, so I'm sure that when Jack advises Chris where to slow down and what to emphasise in that song, it is actually Prof. Diamant who is the guiding force.
