Kermit the Frog Was Just Trying to Put on a Variety Show. Fifty Years Later, the Muppets Are Some of the Biggest Stars in Television History

That show was appointment viewing for me back in the day. Not only were the Muppets themselves incredible, they had some awesome guest stars - I remember Elton John, Peter Sellers, Julie Andrews, Alice Cooper, Vincent Price and Mark Hamill, among many other.
