So in the the for sara tape (which you can listen to on YouTube) there is a section of audio where who we can assume was wirt's dad is using the cassette tape, & in the album by the blasting company sketches of the unknown during the song of the same name we can hear a baby crying in the background. I believe this child is the same young wirt in the for sara recording & wirt's dad was setting up the cassette playing to record the piano song in sketches of the unknown. I also feel like there is some meaning behind these song titles in sketches of the unknown but I'm not sure what.
