In celebration of the new Muppets movie (which was amazing!), I’d like to take this opportunity to post one of the greatest performances in the entire run of the superlative The Muppet Show. Paul Williams singing his own “An Old-Fashioned Love Song” with an open vulnerability, the kind of melancholic grown-up tune that made The Muppet Show occasionally arresting television among all the wonderful silliness. And you have to love that one Muppet who looks exactly like him. No wonder he came back to write “Rainbow Connection;” every guest on this show, from Mark Hamill to Levar Burton to Peter Sellers to Linda Ronstadt to Mr. Williams, looked like they were having the best time with our felt friends.
