Sad times.
I had a feeling it was coming with his failing health, but it's still a shock and hard to believe it's true.
I had the opportunity to view a gallery of his and participate in a group Skype conversation with him on his last birthday (we sang to him, it was quite fun). He was very kind and gracious. He signed off with a live long and prosper, something I believe I will never forget.
Very sad.
