I just watched my DVD of Jim Henson's Memorial Service that I just got in the mail today from Ebay and it was one of the most emotional things I have ever seen in Muppet history. Here are the most tear-jerking moments (to me) from that beautiful memorial service.
Big Bird singing "Being Green"
Dave Goelz singing "I'm Going To Go Back There Some Day"
The Muppets singing "Just One Person"
When Big Bird sang "Being Green" you can tell that it was so hard for Caroll Spinney to sing with out crying. And that just really got to me.
