Yeah it was quite odd timing! It was a surprise to hear of his passing, he seemed to be in pretty good shape, though I had missed that his lifetime of smoking had not long ago resulted in an illness that required him to have oxygen to help his breathing.
I did also notice that his YouTube videos had slowly stopped being released, with the last ones on there some recent interview type shorts on people's lives. Seemed like an interesting idea. A shame to have lost such a unique creative.
