Gene Wilder!!!
Nancy Reagan, Muhammad Ali, Patty Duke, Merle Haggard, Doris Roberts, Zsa Zsa Gabor (I know this was very recent also), Garry Marshall, Gene Wilder
These as well as Debbie Reynolds and George Michael are probably the most prominent I see. Thanks for all the listings, posters.
Glen Frey was quite a celebrity but I have a harder time seeing that when he is part of a group. I never got much into celebrity, which includes bothering to know the individuals in a singing group, so it has to reach a certain level for me to know the person (I know many of those listed, just don’t know if I consider them truly at the level most people would’ve heard of).
