Kermit the Frog is a Muppet character and Jim Henson's most well-known creation. Introduced in 1955, Kermit serves as the straight man protagonist of numerous Muppet productions, most notably Sesame Street and The Muppet Show, as well as in other television series, films, specials, and public service announcements through the years. Kermit performed the hit singles "Bein' Green" in 1970 and "The Rainbow Connection" in 1979 for The Muppet Movie, the first feature-length film featuring the Muppets. The latter song reached No. 25 on the Billboard Hot 100.
