I am very sorry to read of the sad news. My memories of Clayton go WAY back to his early days @ Redwood & Ross in the late 60's! I remember he used to order vanilla milk shakes 'with an egg' at Pipers Drug Store as I'd often see him in there for lunch when I worked at a nearby shoe store. Later I remember him @ McArthur's.
Hopefully, memories of happier times will help assuage your sorrow.
I'll say a prayer for his soul and for your comfort.
