Very sad news to hear. One of my life's regrets is to never have seen Floyd in their original lineup. Many years go, I had a change to see them at the Mile High stadium in Denver, CO. Trying to save my first marriage, I gave my tickets to my bro. He was nice enough to bring back a "Wish You Were Here" T-Shirt. I ended up divorced anyways. There's a moral in that story I'm sure.
RIP Richard. You will be missed.
