Hey, get this everyone... I'm an avid listener of "The Dr. Demento Show". It's a nationally syndicated radio show dedicated to comedy/novelty music and sketches, and related things. ANYWAY...Dr. Demento played a double dose of "Mahna Mahna" this weekend when he played The Muppet Show version preceded by "Mah-Na-Mah-Na"-From The Movie "Sweden Heaven And ****" He then went on to say that this was the original version from "a skin flick from the 1970's" (!!!) Dr. Demento said something like, "The Muppets never included skin flicks, but they knew a good song when they heard one!" Now the truth can be told!!!
