Stevie Wonder (b. 1950) made a guest appearance on a 1973 episode of Sesame Street. He performed "123 Sesame Street" and his hit "Superstition," and talked to Grover. Many of the street scenes from that episode were repeated on the show as inserts.
Kermit the Frog and the Electric Mayhem interviewed the musician in the Spring 1984 issue of Muppet Magazine.
He appeared in "Yakety Yak - Take It Back", a recycling PSA that eventually aired on Sesame Street.
Bob McGrath sings Stevie Wonder's songs "You Are the Sunshine of My Life" and "Isn't She Lovely" on the album Bob Sings!
In The Muppets episode "The Ex-Factor" it is revealed that Wonder's song "You Are the Sunshine of My Life" was Kermit and Miss Piggy's song when they were dating.
