Muppets: Mahna Mahna Posted on Thursday, January 10th, 2013 at 7:29 am. PTWritten by Jim Dalrymple I love this little guy. Moeskido I love that these particular Muppets predate Kermit. Fox While these Muppets definately date back to the first season of Sesame Street (can you tell me how to get there) in 1969. Kermit the Frog was a Sesame Street season 1 regular and as one of Jim Hensons oldest creations, appeared as far back as 1955′s Sam and Friends.As a child of the seventies who grew up watching Sesamie Street, the Muppet Show and other programs of the time (Electric Company) I’ve always felt that a little piece of my childhood died with Jim Henson in 1990. Moeskido I stand corrected. gjgustav Also worth noting the song first appeared in a Scandinavian soft-porn movie.
