Wow, it's nice to meet you, Amanda! As you can see, we're all quite fond of your uncle around here (some of us more than others; Sara, I'm looking in your direction...).
I kind of figured Richard had been cremated, since St. John the Divine, I learned, has no cemetery, only a columbarium.
I'd honestly have to say that your uncle was my favorite of the main Muppeteers; I've loved his characters, especially Scooter, since I was a young girl.
Also, in honor of Richard's birthday on the 16th, we set up a special thread in the Henson People forum.
Once again, nice to meet you, and do swing by again!
