"The Baby Tree", written by Rosalie Sorrels, is about an imaginary island where babies grow on trees and are collected by happy couples when they fall. The scene develops over the remaining album side, in "Let's Go Together" and "A Child Is Coming", that a couple is among the gathering in a park outside Chicago the night before the hijacking, tripping on acid as dawn approaches. She reveals that she's pregnant, and predictably they resolve to free their child from the government's "files and their numbers game" by joining the hijackers. In this setting, "The Baby Tree" can be seen as their acid-induced daydream about pregnancy, and so fits neatly into the narrative. The allegory of "Let's Go Together" and "A Child Is Coming" symbolizes Paul Kantner and Grace Slick's romantic relationship and Slick's pregnancy by Kantner, which would result in the birth of their daughter, China Kantner, the following year.
