I realize there are a good number of threads dedicated to Mahna Mahna and his appearances, but there are some aspects to Mahna Mahna/Bip Bipadotta that elude me. First of all, this is the version that appeared on Ed Sullivan and perfoemed the song "Mahna Mahna." He has blinking socket eyes. Second, this is the most famous version who appeared on the Juliet Prowse epsiode of The Muppet Show and performed the song "Mahna Mahna" with two Snowths just like he did on Sullivan (and probably the same or similar one that Bill Barretta performed in The Muppet Show Live). He has blinking socket eyes, but longer facial hair than the Ed Sullivan version. This pupil eyed version appeared on Sesame Street and sang the song "Fat Scat Cat." He sang "Give Me Lots of Air" on Seseame Street wearing shades like this after I believe he was renamed to Bip Bipadotta. I wonder then, who is this, who performed the song "Mahna Mahna" on Sesame Street? Also, my "Jim Henson: A Sesame Street Celebration" CD credits the song "Air" (different than the one I mentioned above... it's the one that goes "Air, air, air, come for your suply today. Air, air, air, from Maine to Monterey) to Guy Smiley. I seem to remember MC Radio once crediting this song to Bip Bipadotta. Was this an error, or is there another version? Feel free to add any instances of other variants of Mahna Mahna/Bip Bipadotta.
