Raposo's considerable stylistic ambition during his tenure as music director lent "Sesame Street" its trademark extreme musical diversity. For "The Electric Company", particularly for songs he composed for the Short Circus, he led CTW to pop-record production values and generally strongly enforced an adult musical sophistication for all content he supervised. Given an unusual creative freedom in the Music Department at 1970s CTW, Raposo toggled from convincing country ballads (e.g. "The Ballad of Casey MacPhee," which depicted Cookie Monster as a heroic train engineer caught in a mountain avalanche) and authentic hillbilly ("It's a Long, Hard Climb, But I'm Gonna Get There" and "The P Song," among others) to blues elegies of considerable emotional and tonal complexity, like "New Life Coming" and "Bein' Green."
