I spent an hour or two last night watching Johnny Winter clips on YouTube, including an interview from March 2014 in which he looked very frail and seemed to be having trouble breathing, which was sad to see.
There are some great live clips though, I love that supercharged version of "Jumping Jack Flash" from the Old Grey Whistle Test.
It even inspired me to pick up a guitar and actually play for a bit, which I haven't done much recently.
