Over the many years and many, many people he has taught/flown with, I'm sure there are thousands of stories involving Graham.
I will always remember my PPL test. Sheldon (current Moruya Aero Club CP) was in Moruya for a couple weeks doing his instructor training and instead of sitting around the Aero Club, Graham asked if he wanted to ride along in the back seat. We flew from Moruya, touch & go at Wollongong, then my first ever landing at Bankstown , over to Goulburn and back to Moruya.
I was worried about navigating my way into and out of Bankstown, having only ever seen Sydney from the ground a dozen or so times. Listening to Graham's calm voice explain where everything was made things a lot less stressful in the cockpit ... he was always so calm and collected ... and I found Bankstown!!!
For a few years I spent almost every weekend at the Aero Club and Graham was always happy to come in early or stay late to explain things I had trouble with or just have a chat. He had a knack of easily explaining things that I couldn't understand from other instructors. Graham helped to make my aviation experience an enjoyable one and he taught me a lot. As I said in the other thread, he will be sorely missed by the aviation community.
