The Song:In order for it to feel more authentic, Beck filled out his
Song Reader book with fragments of songs and melodies, as well as fictional album collections and song titles. On the back of "Saint Dude," there are a number of albums listed, including the most sensational collection of songs,
Prison And Mountain Songs (For Boys). "Pst Pst Pst" is listed as part of that.
Many, if not most, of the songs on the back of "Saint Dude" are references to older sheet music. "Pst Pst Pst" is half a reference, as there is an old sheet music song from 1927 called "The Whisper Song (Pst! Pst! Pst!)".
