I updated the main page a few minutes ago to include a section on John. I'll gladly change it if you feel it's necessary.
Here's how it currently reads:
“John Henson (1965-2014): John Henson, the forth of Jim and Jane Henson's five children, died Friday, February 14 at the age of 48. He served as co-owner and board member of the Jim Henson Company and was active as a performer, most notably as Sweetums in various Muppet productions for over a decade. Henson also originally portrayed the Coca-Cola Polar Bear for live appearances.”
