From Denise Rimer Hardman, Clay's sister: 

Clay Daniel passed away peacefully on September 12, 2018, at Tranquility Hospice.  He requested cremation with no memorial to speak of.  SouthCare is handling his cremation and has a website for you to say anything you'd like to Clay. It may not be available today but I will definitely check on it tomorrow.
Having spoken to a couple of Clay's good friends, I realized that it is imperative for him to be remembered in some lighthearted but significant way.  We will plan a way for this to occur in 3-4 weeks.
