I wasn't sure if that program was broadcast nationwide, Trevor. There are lots of practical tips on those programs and John made it all sound easy.
He was one of the old school! I was introduced to him by my sister and her husband (his cousin and same surname)
John was in fine form. I brought a slip of a plant along for identification and he was able to tell me what it was immediately.
My sister told him about Ideas Genie. Like so many people in those days, he didn't see why anyone needed a computer program for plants! When I heard the bad news yesterday, I was rather surprised to find that he had a computer!
I can well understand that he would not have had a lot of time to spend on it.
