In looking for that last link, I think I opened up a great big box of trouble for myself. Yes, it turns out there is a great deal of Muppets on YouTube. Who’da thunk it?
I love Harry Belafonte, so finding that little gem warmed the very cockles of my heart. And I’m not sure when exactly the Star Wars bit was made… either it was right at the time, in which case I guess Mark Hamill really was the star you wanted, or it was a lot later and Mark Hamill was all you could get… looking at Hamill, I think it’s the former, because he’s not toooo ugly yet.
