Produced in late October in 1977, Elton John guest starred on the 214th episode of The Muppet Show.
Sam the Eagle asked Sir John why he dressed up like "a stolen car", while Kermit defends the man saying that musicians who are as celebrated as Mozart have always dressed extravagantly.
Another character, Scooter, who appeared to be John's biggest fan introduced him as "the greatest talent in the history of the universe".
Watch the full performance above.
The episode aired in early 1978.
