Just read this on Facebook. Not sure it was Covid-19 related - I think he was in hospital for other reasons when he had a heart attack and a stroke.
I've always known about Charles with his connection to Star Wars and Alien, but only made contact with him fairly recently when I was trying to help USC make contacts for their Alien 40th anniversary exhibition. He wasn't able to help me, but once he found out I had contacts at Fox he asked me if I could put him in touch, and I believe there was a book of photos from Alien (and possibly the hours of interviews he had on cassette) in the works with Titan.
He was constantly putting up pictures from Star Wars, Alien, Judge Dredd and Flash Gordon and frequently engaged with fans. Plus he was a lefty, so bonus points there. I never met or spoke to him other than the occasional exchange via Facebook, but I shall miss him.
Deepest condolences to Bumpy.
