Michael Davis has some juicy tidbits in an interview with CNN from his book, “Street Gang: The Complete History of Sesame Street.” He says Joe Raposo and Jeff Moss, who wrote the show’s songs, were locked in an intense creative competition. In fact, he writes, Raposo “fairly seethed with envy” when Moss’ “Rubber Duckie” became a Top-20 hit. Davis also says that producer Jon Stone was “the Orson Welles of ‘Sesame Street.’ … Without him, the show wouldn’t have been what it became.”
