Ian,
One side note I hope doesn't hijack the thread.
Friends of mine that were close to Mr. Jones when be built the Cashen course at Ballybunion told me that when the club was scheduled to have the course opening they asked Mr Jones if there was anything they could do for him, anything he really wanted to celebrate the event.
Apparently, Mr. Jones broke down in tears and said the one thing - the only thing - he really wanted was for his sons to attend the event.
Honestly, my memory fails me so I am not sure, but I think one or both did show up. Kind of sad, obviously.
