Good Morning Moon (and other songs) on "Make Me Smart"
The guitar and whistling from Good Morning Moon is playing behind the callers at about 14 minutes into this week's "Make Me Smart" (23. The Righteous Mind) with Kai Rysdal and Molly Wood. Molly credits Marian at the end of the episode (I couldn't pay as much attention during the rest of the episode to recognize the other songs used for background).
