someone has composed a Checks and Balances song for basic educational purposes https://www.youtube.com/watch?v=s07lk6rMWpU
"Learn about the Checks and Balances in the U.S. Constitution and government. Separation of powers is a very important concept stemming from Enlightenment thinkers like Montesquieu. The Executive, Legislative, and Judicial Branches come to life in this music video by the Social Studs. Music by the Social Studs. Also, check out the "Bill of Rights Song" by the Social Studs. http://SocialStudsRock.com "

and there is a "Three Branches Rap" from "Smart Songs" "Clever, memorable hip-hop songs from rappers Shoeless Jeff and Scott Free offer a fresh and innovative twist to learning about U.S. government."

not quite what I had in mind, but may be a starting point
