The lead guitarist from REO Speedwagon Gary Richrath has passed away at the age of 65. He was kicked out of the band many years ago while he was struggling with alcoholism, but they did reunite for one night in 2013. (The video of that appearance is at the link...and it's really hard to watch. He looked terrible--although he could still play).
I prefer to remember him this way, jamming on my favorite REO song...
