Are you aware of Mozart? It’s kind of the same timeline.
I wouldn’t normally put the Muppets on the same cultural plane as Mozart, but sure. And maybe they are. All the celebrity deaths that happened the week after the Muppet episode had a Muppet connection (they appeared on Dolly’s show, Jaye Morgan was on the show, and Tim Curry was in a Muppet movie). So maybe the Muppets are on that plane.
