Cassp: It is a true loss when you lose a dear friend. I do understand, it's like part of you has gone.
I'm now 73, and have lost three preciuos friends, all Technics keyboard players, I miss them, there is no way to replace a friendship with a long history. At least not at this stage of life.
All this does leave me with the thought that this is all part of a much deeper meaning, more than I can understand right now.
Live with his memory, it must be precious,
John C.
