Sesame Street changed TV by using music to help kids learn how to spell and how to share. Singer-songwriter Anya Rose and the group Ants on a Log write social action songs to help children in primary school learn edgier lessons, about problems from environmental pollution to racist and sexist behavior - inspired in part by 60s satirist Tom Lehrer. After hearing these tunes, the 9-year-olds in your family might feel inspired to research a problem in your own neighborhood - and then write your members of Congress about it!

Now that Judge David S. Tatel has retired from the U.S. Court of Appeals for the D.C. Circuit, he feels freer to warn us all: the Supreme Court is threatening America's democracy by inventing spurious legal doctrines and grabbing more power for itself. There are also lighter moments in this revealing interview, as David pulls the curtain aside and tells us how the judges on this powerful court really do their work. Spoiler alert #1: It used to involve a red children's sand pail. Spoiler alert #2: Because David is blind, he used to hire "readers" who rattled off every word of laws, books and briefs out loud to him, at such mind-boggling speeds that most people couldn't understand them.

David Tatel - who retired recently from the U.S. Court of Appeals - has led what he calls a "braided life" that intertwines hardship and accomplishment. With his wife, Edie, he describes how he struggled to hide his gradual loss of sight from friends and colleagues alike - including tricks like counting rows and seats in a movie theater and following the clicks of high heels. Meanwhile, David became an accomplished lawyer who fought landmark civil rights cases. You can read their full story in David's new book, Vision: A Memoir of Blindness and Justice. David will return in Part 2 to take us behind the scenes of the second most important court in the nation.
